found some old incomplete blends, changed the materials for PBR ones and baked. I think I baked the albedo as srgb when it should've been linear, since the normal and roughness were, but I forgot.
here's the scene with the light tubes instead of omni-lights:
I also made a texture for using as projector mask with the flashlight. it's barely noticeable but it does help the atmosphere:
REVBENT just a different idea i had looking at the room... feel free to use it or not.... the center light could be like a projector, and below it you could have a sun of sorts as a ball of light. The classic projector rays leading from the outer edges of the fixture so your eyes understand its a "hologram". It would feel very alien i.m.o.
I havent though of what to add to these rooms, for now I'm making corridors and rooms. a hologram is a good idea.
I will slowly make assets to fill these rooms, I need to put interesting things so the levels don't feel repetitive.
REVBENT you seem to have the headroom to the ceiling. the same way of lighting could be applied to street lights, wall lights, beam lights, and the sort.
the whole scene is using a VoxelGI, It doesn't "need" lights, but I added spotlights to cast shadows on moving things like enemies. In this last screenshot I actually removed 4 lights.
