Quality Issue

Hey guys,

I'm working on 3D furniture configurator and I'm stuck. I'm not sure what is the best way to lit the scene. I mean best value between quality and speed.
There is lot of color/decor combinations so it's impossible to bake all the textures with GI and reflections.
I need as much realistic output as possible.
Some textures are blurred and not sharp enought even I set them to highest possible resolution. Some of them are nice and sharp. Really don't understand.
Another limitation is file size. Must be less then 50mb because bigger file size is ignored by cache.

Really appreciate your help guys !

Thanks !

 

If you need HI-Resolution textures and a small build size , you could use substance's if possible.

They generate on start-up / runtime and do not eat much space.
Make sure that your quality settings are not reducing the texture resolution. The happens on the lower quality settings.
You could bake AO per object but GI i don't see working in your case.
For reflections you should take look at qubemaps and eventual box projected qubemaps (not so easy)
