Pencilart, you have multiple problems:
- first the only active light shown is a ceiling light. How a ceiling light can have an effect at floor level, will you ask?!? The height of a ceiling light is equal to the height of the wall end closest to the room center (I know this algorithm isn't perfect but it's the way it works in the current version). In your case, this closest wall is the one under your shelves behind the camera and is 36 inches high.
- second I don't know where you got the "BasicPlusExtraLights" and "basicLights" lights, but as they have no "classic" bulb icon, I suspect you imported these lights from an OBJ file. This can't work this way; You must use lights coming from an SH3F file, either basicLights.sh3f or BasicPlusExtraLights.sh3f.
Conclusion: import SH3F files containing lights, replace your 3 lights by some coming from the SH3F files, and turn off ceiling lights to avoid the problem with your small wall.
I hope this will help...
