The look I’m going for is photo-real or very close. I’m still deciding on what game engine to use, I’m thinking Godot, or maybe Unreal Engine.
Q 1. I’ve read about putting multiple assets’ textures on one set of maps. I believe this is called an atlas? Is this a useful technique for game assets? Is it better in some way?
Q 2. How obsessive do I have to be with everything being the lowest-poly possible? For example, should a metal balcony railing be a cube with lots of transparency so it looks like it is open, or should it be modeled? Should low-poly ivy be a single plane or is a 50 face group of vines okay?
Thank you for your help!
