Man the longer I take between updates, the more I feel like I need to show, which leads me to not updating again.
nedwork - I took your advice and added a stronger cubemap. I haven't touched it up yet though, so it's jaggy. I also added some more office stuff. I agree the textures could use a little more work, since they are mostly just AO. I'm going to devote my last bit of polishing to the textures for sure.
Here's what the office looks like now. There's some obvious lightmap seams on the ceiling/floor because I'm just using modular pieces at the moment.
I'm going to make some trash bins, some kinda painting/wall art, then finish the markerboard. Outside on the lower level, I think I'll make a bench and then I'll be done with all the models.
I made the lighting in the lobby area darker overall. I tried to create some more contrast by using a blue skylight and using a warmer color for the spotlights.
It's not the sterile white I initially imagined, but maybe it's more interesting in a way.
