So the last few days I've been working on the door (and the window above it), ceiling, and overall efficiency for my level. I condensed many materials so that I now only have a handful to deal with and I've made many instances to use for my various textures masks. Essentially I'm streamlining my materials so that they can be changed easily on the fly. Today I took some time and created the normal for the dome in Substance Designer. It's not complete yet but I'm liking how it's turned out so far. I want to add some base color and roughness maps to it next and I might end up hand painting the battle scene at the bottom. Not sure yet. Right now it's just some image I grabbed off Google as a placeholder.
I received some feedback that previously my level was a little too dark, especially in the corners. At the time I couldn't find the settings to help increase it inside UE4. Now I've found several settings that can up it from various sources and I think it's actually a little too bright now. But I'm not too worried about all the lighting settings yet. I still have a LOT of work to do with just creating meshes/textures. If you look closely, some of the objects in the scene actually don't even have a material assigned to them.I'll keep plugging away...
