Hello Venessah,
I assume you are using mental ray for your rendering?
Check my render/bake tutorial here for some tips: http://amis.diinoweb.com/files…..baking.rar
There is no easy way to explain you how to light a scene. You can check few things like:
- Final Gather ( FG ) must be turned on – indirect illumination
- Omni lights must have shadows turned ON.
- Sometimes you may need to turn on GI ( global illumination ) again in Indirect illumination menu.
Best solution is to search google for interior lighting with 3ds max and mental ray , there are allots of nice tutorials and they will explain things allot better with pictures or video.
Wish you luck.
Best regards
