Week 4 and 5

General / 07 February 2020

I spent a couple of days trying to figure out the elevated train tracks in the scene. I made half the bridge so I can just mirror it and propagate it, to save on the tri count. For this bridge I read a technical document on steel structures, which gave me the right key words to find more technical drawings of how steel bits are joined to each other.

Technical drawings reference


I also used pictures of the elevated train tracks in Chicago and the old New York ones for real life reference.

Chicago and New York elevated train tracks


Since the bridge is elevated and away from the camera, I decided not to chamfer it. The bolts will be baked into the texture of the joinery, while the rest of the bridge will be textured with a tiling texture (we will use macro noise and decals to make it less repetitive).

The other element modelled this week was the skybridge. I was able to find pictures of the original skybridge in the concept. Modelling it did not take long as I divided it into modular pieces and just repeated the same geometry across. Again, as they are really far away from the viewer, I did not chamfer the edges and they will be textured with tiling textures.

The last thing I modelled was a tunnel and gate for the train to enter the building. It is really hard to see what is going on with that in the original concept, so I found an Art Deco archway to base my gate on.

I simplified it a bit so it is readable from afar, where the player will be. I kept the stripey details, but made them chunkier.

During these past two weeks, I also made some of the tiling materials for the walls. These were made completely with Substance Designer. To choose which materials I would make, I got many pictures of older New York buildings, and had a stroll on Google Street view. I noticed most of the older buildings facades were made of limestone, but also red brick and cream brick. Our main building (the one with the Atlas on top) has a limestone facade on the ground floor, and cream bricks on the rest. I kept the materials pretty clean so they will not be very obviously tiling, and intend on adding variation with decals.

I already made two versions of limestone in order to vertex paint it, and a brick mask that will be used on top of the original material

One thing I noticed on the reference images is that New York has a very boring and ugly pavement, made of very large concrete slabs. But we are not necessarily making New York, just getting inspired by it. So we decided it would be nice to add some jazz to it. We are going to have part of the pavement being plain slabs, and a part of it having a subtle Art Deco pattern.

The building generator Sophie is making is getting really nice! I cannot wait to use it and fill the scene with buildings, but it still not ready. So the scene still looks like an early blockout. This is how it is at at the moment:


Final Major Project - Week 2 and 3

Work In Progress / 27 January 2020

I'm writing the post for week 2 and 3 together because we spent some time this week fixing our portfolios, writing CVS and cover letters, applying for jobs and having an interview. The project is a little late but I think we can recover.

I finished modelling the base modular kit for the buildings. This is sufficient for Sophie to continue testing the building generator she is creating. This kit is still missing balcony pieces and maybe a roof variation piece (still have not decided). This is what the kit is looking like right now:

Modular kit detail 2


We decided to have 90° and 45° angles for the corners of the buildings, as there is probably not going to be enough time for Sophie to work out another way of doing it (she has quite a lot on her list). Modelling the 45° angles was very tricky, especially for more complicated pieces like the roof separation. It may seem like using symmetry instantly solves all problems, but it does not. To know where to place the symmetry mirror, and make sure the pivot is in the right place (so the generator can place it correctly and aligned with other pieces), I had to use a whole bunch of maths I had not touched since middle school (and I am a mature student, so that was something like 13 years ago). Fortunately, there is a triangle calculator that was very helpful, suggested by Sophie. I will not bore you with the details of how the 45° pieces came to be, but they took a long time to get sorted.

On top of that, we also had to change the pivot points of all the pieces once, and rename all of them a couple of times, but I think now we're on track.

Every little variation created to, well, add variation to the scene, was a new can of worms to solve. This has also delayed the creating of the kit quite a bit. I am constantly bringing the pieces into Unreal Engine to test them, and that is when I catch most problems. For instance, the Ground Floor pieces are taller than the mid building pieces. So corner pieces and pillars had to be made especially for the ground floor. One of the ground floor varieties include a "skirting board" (not really, it's more of a concrete detailing, anyway). This meant I had to now make pillars and corner pieces for that variation (a plain 90° corner piece, a decorated 90° corner piece, a plain 45° corner piece, a decorated 45° corner piece, a plain pillar, a decorated pillar, and a plain wall. For this reason we will probably not add any more variation to the geometry, and try to differentiate the buildings with materials, pillar placing, and decorated pieces.


Pieces and corners that were too short for the ground floor


Pieces without skirting not matching


I got a bit bored from modelling and decided to start with the materials for the scene. The first one I chose was asphalt. Here are my references (however I also looked out the window at the road by the university building):

Asphalt reference


We decided to make 3 asphalt variations, and later on we will use a splat map to distribute it around the floor plane. This shader might become more complicated later on, as we intend on adding puddles of water to it. I made the materials quite pristine, without cracks, as to not tile too much. I will add cracks as decals later on. We will also have a macro roughness on top of the smaller tiling roughness, to add more roughness variation.  I used a tutorial as a base for the material, but I have changed it quite a bit, eliminating the cracks and stains from the original to avoid tiling issues.

Variation 3


On week 3 I also spent a long time researching existing buildings in New York and the material on the facades. I went into Google Street view for screenshots, and also read many articles about famous New York buildings. After that I plan on making the following materials for building facades: red brick, cream brick, plain limestone, limestone bricks, limestone squares and limestone stripes (the plain limestone will be the base for all other limestone materials, how these are going to be constructed is still uncertain as we have a few options to consider).


Final Major Project - Week 1

General / 13 January 2020

Week one started with the hand in of the previous project, plus a couple os days preparing CV, portfolio and applying to some jobs, so it was not particularly productive towards the FMP. We ended up only working 2.5 days on it. This is the chosen concept art we'll base the project on, made by Eddie Mendoza:



I am making my FMP with technical artist Sophie Pette, and because it is a group project we started by organising a Trello board with a break down of tasks so we know we are on the same page.


Next we gathered references. We can see the concept was heavily inspired by New Work buildings so we gathered both current photos of buildings and 1950's images of the city:



  


We also looked into the Chicago train tracks for inspiration and reference:



We have also set up PerForce so we can both work on the project at the same time.


I have started the blockout but it is not ready yet. I needed a break from it and went to do some of the modular pieces.


We are not actually modelling the cars, however I am using them for reference on the scale of the city. It is particularly challenging to understand the scale without windows, doors, people, etc. So I will use some of the modular pieces I am making to keep blocking out.


One of the challenges we know we will bump into is the fact that the original concept looks like a busy city, with all its people and vehicles. We don't have a character or vehicle artist, nor do we have time to model those things, so the city will be empty. We decided to embrace that and we are working on a narrative that will explain why the city doesn't have anyone in it. More details to come later.

Garage - Week 5

General / 06 January 2020

In week 5 I finished some small props and textured the oil drum and tires, as well as finishing baking and adding texture to the tool box. This was done in Substance Painter and Photoshop for the labels. I tried to loosely recreate some vintage labels I found online with free fonts downloaded from DaFont and 1001Fonts.


I used some posters and metal signs found on the internet to give the place a little life. All of them were brought into Substance Painter where they were altered to give them ageing marks, and roughness and metal information. 

The poster about safe winter driving was taken from this website, and the Goodyear metal sign was taken from this website.


The Goodyear sign in this picture was taken from this website. The pin up was taken from this website


To give the place some atmosphere, I have made god rays with the same technique used in the Captain's Cabin, but I made a new texture for it with animated "smoke" and particles. On top of that I added some particle effects that were made mashing together these 2 tutorials:

The scene was still lacking the sci fi element the brief demanded. I made a sci fi wheel with glowing emissives and cables and placed them on the workbench. For the glowing emissive and light, I made a blueprint and followed and altered the following tutorials:

This is what my own light function and pulsing emissive material look like:

The sci fi wheels where based on this concept by Jomar Machado (but I changed it a bit):


This is the final outcome:

For the cables I used splines utilising the same method I did for the fairy lights on my previous project, and just changed the colour within Unreal Engine by multiplying a colour by the albedo. The cables helped to fill the scene and make the sci fi wheels look more sci fi.




I have also added some decals to make the scene dirtier:






The stain decals were made in Substance Painter with a range of the software's own brushes and alphas. The tire marks were initially made in 3Ds Max with the geometry I used to make the highpoly tires. I copied it over many times, then used the bend  modifier to make it less straight. I then proceeded to bake maps within 3Ds Max, and used them in Substance Painter to finalise the decal.



I also wanted to make a video to present my environment, and followed this great tutorial in order to do so:

I made the video into a gif using EZGif.com

I made more materials for the garage, starting with metal:

Next I made cast iron:

For the formative hand in last week, since I was very late with everything, I just applied a world aligned material to most things that had not been textured yet. This week I will be baking and texturing any remaining props.

The scene was still looking very empty (it was also missing a car, but that was a problem for later). I asked my peers for advice and my colleague Ashley Brocklebank, who is a concept artist, was extremely helpful. He suggested getting some mid size props to fill the space, which resulted in modelling oil drums and tires, then scattering them around the scene. They really helped to fill the environment:

I finally finished texturing the hero prop, which felt like a brief of its own. I used this prop to learn more about texturing in Substance Painter. I had not used smart masks before, and had a shallow understanding of generators and using the baked masks in fill layers to get different effects. For this prop I used a little bit of everything and made sure to avoid destructive workflows as much as possible. To match it to the original piece, I had to make all logos and written and drawn bits on Photoshop (except for the bottom one in the body, I was able to find a great image of it online which only needed some warping to work. I also changed it in Substance Painter by adding grime and dust). The prop is missing some buttons and wheels, because I will use the same meshes across it to save on texture space.

This is what it looks like in Unreal Engine for now. I definitely need to improve the lighting to show it off better:

This week I finally sort of finished the car, enough to throw a blanked on top of it. The base cloth was made in Marvelous Designer, then brought into Zbrush to add some more detailing, like random smaller creases. For this I used the free Poliigon fabric brushes, which saved me a lot of time. I then baked the fabric with Marmoset and brought it into the scene. It still needs to be properly textured, and is currently on the list with all the other things that need texturing.

Garage - Week 3

General / 03 December 2019

Modelling and baking the hero asset took 4 days as it was much more complicated than I expected. It is finally done and I am currently texturing it.




Since this project doesn't have a texture budget, I decided to bake most props from highpoly models to showcase my baking abilities. Unfortunately this greatly increased my modelling and texturing time, which means I still do not have many props done. Also garages are messy and require a lot of meshes to look full, especially because this particular one has to be big to accommodate a Cadillac (a car which is 5m long!). These are some of the props I have been working on:



I took a break from modelling to make some materials. I started with the corrugated metal for the ceiling:

The next one was a plastered but not finished wall:

Lastly I made some raw wood for the beams:

Today I started working a little bit on the lighting for the scene. This is the reference I could gather for it:



At the moment it looks like this (but it is not finished by any means):



I would like to make the shadows on the opposite wall to look softer and less defined. This is still very much under construction. Bringing the light angle on the directional light up smooths the outside of the shadow, but not the individual "blades". I'll be experimenting with that this week.

1950's Garage - Week 1

Work In Progress / 25 November 2019

This week I started the last 3 weeks project before FMP. The brief is 1950's Americana, and I decided to make a garage with a Cadillac inside.

This is my initial moodboard:



This week I have been modelling the building and started modelling the props. Today I had a try at modelling the car which is extremely challenging for me, as the car I chose is fairly complex and strip modelling is definitely not my forte. If it turns out I can't make the car well enough, I plan to have a fabric on top of it, as a car that is being worked on in the garage.

To make it look like a 1950's garage, I want to have some period props such as a fridge, posters with 1950's advertising and this really cool engine tester:

For the mood, I want to play with lighting coming through blinds at the end of the day. I want the scene to be a little moody, so I am also intending on adding a lamp on the workshop table.


As I'm not a vehicle artist and having such short time for this project, I'm planning on making a rough Cadillac shape and then cover it with a canvas fabric, like a car that is being worked on. I'm aware I probably won't be able to finish the car in a good standard. I think the canvas fabric will also add narrative; working on this car is a half abandoned project and the garage is not frequently used. I want to make a Cadillac 1959 Eldorado Biarritz. This is my reference:


I was lucky to find orthographic views for it, and a 3D model with wireframe. I also asked my colleague and vehicle artist Max Ramsey for advice on how to approach it.

By the end of the first week I still don't have much on my scene. The car is only half started because I decided to prioritise other props I know I can deliver to a higher standard. The car will be more of a stretch goal. This is what I have at the moment:





Conservatory - Wrapping up

Making Of / 18 November 2019

I finished the conservatory last Friday with some new additions.

I wanted to make the place cosier, so I added a cushion on the chair which is actually just the same as the pillow but with a different colour multiplied into the albedo, and I made a rug too. 


Nothing new to the pipeline here, I just made it similarly to the duvet using Marvelous Designer. I also made a tiling material for it and used a baked normal with Angle Corrected Blended Normals in UE4:

I finally got to make my ivy which I thought I would have no time for and I'm really pleased I could. I made ivy branches in a way that could be used to make a plant in a plant pot, but also used outside as a whole plant climbing and coming down the roof.





The ivy branch was made using the classic 3Ds Max approach, out of a spline. I then used the Animation / Position Controller / Path Constraint to attach the leaves into the same spline, speeding up the process of placing, rotating and scaling them. This was taught to me by my supervisor at my placement year, Max.



Here's some fun gifs showing how the environment progressed:


  


Some disclaimers:

The images from the posters were not made originally by me, although they have been edited in Substance Painter. These two images came from the NASA website:




This image was taken from this website and turned into a blueprint by me on Photoshop, then further edited in Substance Painter:


  For the books I also used some images from other sources. This image was from this website.



And this one was from this website.


This Stephen Hawking book cover was taken from Amazon.


Another disclaimer: All light maps and collisions were made by me. I did not use any automated Unreal Engine procedure for this.

Conservatory - Week 4, Day 1

Work In Progress / 11 November 2019

I started this week by making fairy lights for the scene. I wanted to make the scene warmer and cosier and thought fairy lights would do the trick :) This is the reference for them:



For the cable I made a simple mesh that uses a small normal map for the twisting, and used a spline to add it to the scene. The mesh itself is only 2cm in height and has 72 tris. I followed this tutorial to make the spline mesh. This is what the blue print looks like:



And these are the fairy lights in the scene:


For the fairy lights glass I followed this tutorial that my friend Josiah suggested. The inside is made of 2 planes with a masked emissive texture.


I also made a couple of materials and textures today. The first one was a cardboard material:




This is the reference I used:



I used this cardboard to texture this box, and made the sides different because of the way I placed them in the scene. Since the viewer will never see the boxes from more than 2 sides, I could use the same prop from different angles in order to create the impression that I have more than 1 prop:



The second material was Soil:




  This is what the scene is currently looking like:



  

There are some light artifacts that disappear once I bake the lighting in production rather than preview, but since I have been adding new items I have not built the light in production for a little while.

Conservatory - Week 3, Day 5

General / 08 November 2019

Today I put together my terracotta trim sheet and applied it to my plant pots.



  

I just took the materials I had made the day before and blended them using masks:


  

In Unreal Engine I set a blueprint for the UV offset to be random within the 4 terracotta version when the plant pot is moved. I also added a scalar parameter multiplied by the albedo to have a variation on how dark the material is, so I could have more variety even though I only have 4 versions of the material. The UV Offset variable is an array with the numbers 0, 0.25, 0.5 and 0.75 (locations on the UV map where each material starts). It goes through a "Get copy" node with the "Random Integer in Range" having a minimum of 0 and maximum of 3 index (the 4 variables from the UV Offset array). This blueprint was partly a continuation of the one I made for the book cover colour variation in the previous project, plus some help from my colleague and tech artist Sophie Pette.



  


I also finished making the duvet. I used Marvelous Designer to create the high poly mesh (following this tutorial):

I then brought it into Zbrush and used ZRemesher to get a more sensible topology I could work on. I further cleaned the topology in 3Ds Max, bringing  and brought it into Marmoset to bake it. This is how it looks like in Engine:


The material on the duvet is a tiling fabric, and the Baked map is blended with the tiling normal with different UV coordinates:
