Hi!

I am designing the lighting for our new project, but I am encountering a problem. I imported a 3DS file of the kitchen that I created in SketchUp. When I perform my lighting calculations, the kitchen appears completely black. However, when I toggle the lights off, the kitchen clearly shows the light wood textures. I have already replaced the material textures with materials from DIALux, but that hasn't resolved the issue. The strange thing is that the countertop texture works fine, but I cannot get the wood texture of the kitchen itself to display properly.

Can someone helps me please?
