First, this is Vue Professional, not Vue d'Esprit. They are different programs. The former is new and cost $500, the latter is old (on version 4) and costs $200. Second, there are ways to convert most options or settings from one 3D application to another as long as each application has similar feature sets. Most good 3D apps, like C4D, have color, specular, bump, transparency, translucency, reflection, displacement, environment, alpha, and so on for material channels and utilize both procedural and bitmap-based textures. Procedural textures are nearly impossible to transfer, but not bitmaps. There will be differences, but it is not impossible to recreate a scene from one app to another. I was able to do very well importing Poser 5 scenes into C4D with my own plugin, including lights, cameras, textures, and geometry. Third, though, I agree with you that something is amiss in these C4D renders when textures have disappeared. Unless the textures are procedural in Vue Pro, they should be transfered easily. Even more interesting is the fact that the sky was imported, but not the tree and ground textures. When I receive my copy of Vue Pro, I'll run some tests on rendering. I have yet to see C4D's renderer slower than another, but optimizations in Vue Pro could contribute to its speed advantage. Have no idea what options were used in C4D's render settings.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
