Hi BobHstone, I'm really glad you enjoyed our game—your words truly made all the hard work worthwhile.
As you probably guessed, I'm the shader guy. I'm still a student hoping to specialize in Tech Art one day, so my advice and suggestions might not always be 100% accurate.
Umb_28 mentioned that my work inspired you to start creating your own shaders and that you're looking for good tutorials. The Unity Shaders Bible is the only book I've found genuinely helpful so far… mostly because there aren't many others, especially here in Italy.
That book is a great starting point, in my opinion. Most of the effects I used in this project can be edited directly through UE’s Post Process and Material Editor, but the heavier effects should be created using a shading language. UE5 supports HLSL (High-Level Shader Language), which is what I’ve been using.
Feel free to add me on Discord if you'd like to chat more or need help!
PS: i'll leave you a YT channel that i personally like once you got a bit of understanding of shading
