Q: Is Cast Shadows checked in the lights? A: Yes, I want the lighting to cause shadows, else I could just use Global ambiance, but I do WANT shadows. Q: What about Shadow Ambience? A: Shadow ambiance is set to black. All lights have same settings. Q: What is the Falloff? A: No fall-off. All lights are forever and ever ;) Q: Have you tried using a proper texture? A: Well no, but if it wont work with just plain color, then I cant imagine it working with textures. Q: What is the Ambience/Ambient of the ceiling? A: Same as all the other parts of the room. 1 Q: Finally, do you see where the side wall is creating a shadow on the floor? And there's nothing in front of the ceiling. A: Sorry Im not sure what u mean. Whic pic? And pauljs75, that might be something I should look at, not sure about the refraction. I thought refraction only was used when you had some transparency involved.
