Perhaps try selecting everything (go to an orthographic view alt-drag, IIRC, and select everything) then copy everything, delete everything, and then paste what's in your clipboard, and then rebuild all. Maybe that'll work.
Hmm, yeah, might be possible. Probably not feasible in a real game, but cool to think about. Dynamic Parallax Occlusion Mapping with Approximate Soft Shadows (3MB PDF) Natalya Tatarchuk ATI Research, Inc.
5000ft Inc (cmon BoBo, help me out here). Seriously though, I think Ensemble is amazing from what people tell me. Also, Pandemic is said to be pretty nice as well.
The only bummer with Advanced Painter is it won't randomize the rotation IIRC, have to run another script afterwards. Neil Blevins' objectPainter might be better, haven't tried it yet. http://www.neilblevins.com/soulburnscripts/soulburnscripts.htm
Awesome work! I'm sure this isn't the case irl but it'd be cool to see some mountains/landscapes out in the distance beyond the windows. Also some vegetation hanging down from the roof on the outside.
Looks like a good start. You might want to change the color of the sun light to be a bit more warmer and less brighter. As for the arcs, I think they will look better with some deepening into the wall. Like this:
You can see some of the results of that work here. The female character's dress, the black-caped monsters, the pennant flag props, etc. https://www.youtube.com/watch?v=qklBjGf-Arc&t=200
A normal map can be included in a normal from mesh bake iirc Color you can definitely do in Designer but I've not updated Painter so can't be sure (you couldn't prior to 2017.3)
I think mikiex meant that a checker helps you make sure the pixels are square instead of too stretched. IIRC, when anisotropic filtering is disabled, a stretched texture will cause a lower mip to be used.
When I say realistic, I just mean the materials should read as real. It can be a scifi gun or whatever that may not actually exist IRL but it should read like real metal, etc.
