Hey Everyone:)
I just wanted to give you all an update on the train environment that I have been working on. In my last blog post, you will be able to see that I made two Substance Designer materials and placed them into marmoset to see how they would look together. The project is now starting to come together and there has been a lot of progress since my last post. In this blog post, I will show you how the project is currently looking and I will breakdown some of the assets.
First of all, I have made a quick video fly through of the level which you can see below.
You can also see an image of the exterior and interior below.
So as you can see, I now have the two substance designer material (the platform and the train tracks) in a UE4 environment with my train model. At the moment, I am currently in the texturing stage of the project, I have done a first pass of the exterior texturing and I am currently working on the interior. None of the textures are final at this point and I want to keep improving them.
I have been using Substance Painter to texture the train, but the plan is to export out all the masks that I make inside of Painter then make a master material inside of UE4 so that I can control parameters such like the train colour, amount of rust and dirt and so on. This way I will be able make each train in the environment different and make a more interesting and realistic environment. I did a quick test of this method only using base colour which you can see here:
The downside to this method, is that it takes a while to set up as you are practically re-texturing the train and you end up with a lot of masks from Substance Painter. However, once this is set up, I will be able to change each train using material instances rather than re-texturing things inside of Painter and ending up with lots of different textures. I can then use graffiti decals to make each train more unique.
Moving on to the assets. So far I have only modelled the train which is set up in a modular way so that all the pieces snap together, I still need to model all of the surrounding area on the platform and model some filler assets to go in and around the train such as trash. If you read my first blog post, you will see more about how I modelled the modular pieces but in this post, I will show a few of the textures that I have made. Please bare in mind that these are all WIP and could change.
The unwrapping stage of the project took a lot of time! There are 8 texture sheets in total, this may seem a lot just for a train but I wanted to get the train looking as good as possible and this is a train that you can walk through so it's like an environment within itself. Once I have set up the master materials, I can have loads of different variations from the 8 master materials.
You can see two examples of my unwraps in the images below.
The first one is the unwrap for the doors and door frame modular piece and the second one is for all the undercarriage.
I have been working on this project for a while now and I think that I could be working on it for a few more months. This is because I want to get this project looking as good as possible and I would rather go for quality over quantity, I also can only work on this project in my free time after work which slows the development down. You can see below a list of things that I plan to do:- Finish Texturing the train
- Add graffiti decals
- create a snow material and vertex paint this on top of the train or use world position to do this, I'm not sure yet.
- Model surrounding area
- Create master material for each modular piece
That's all for this blog post and I will keep you updated on the progress.
Thanks for reading!
