Hey- If you want I can do the Holiday Inn Riverwalk,Ive got a texture that might work.
It looks way better photo textured. to be honest I dont think rendering cities makes that much of a difference,they look just as good unrendered,IMO. it kinda depends on whether its worth the hassel.
Oh and I see yu missed the big window! just cut the edges of the base texture and make it 4x bigger on the sides and itll fit without sacraficing detial. If this didnt make any sense,Ill explain further.
Edit- Finished the HISA,low polygon and all,the texture is actually from Dallas,One main place,but looks good anyway. search your name at
3Dwarehouse,my name there is " Micro".
some of it is kinda guestimated,but you can fix it up if you want. its also not to scale,I wasnt sure what your scale was.
