Thats just it Ravs, you cant export OBJ from sketchup but (and not being on my normal machine here) I just installed sketchup and Blender and sketchup can export COLLADA directly and Blender imports it directly. If Bryce can import COLLADA files then its all a GO else you need to convert with something like Blender or MeshLab or some other 3D format converter. I should add that there is no need to unzip or change extensions or anything it can go directly. Also, this COLLADA format is pretty cool since its based on XML - I see this usurping the more common OBJ format.
