It seems I have the most problems with the Invigorator rendering engine in these two situations:
1. wireframe materials (it just renders as vector line drawings, if that description makes sense)
2. black or very dark materials (often it just renders those as if they are transparent)
I prefer the Invigorator engine, because it’s faster. But the OpenGL would actually do the wireframe and black materials before. It just stopped all of the sudden. I don’t really know how to troubleshoot my drivers and such. I use a Canopus DV Storm video card, and it is still working on all the other software such as Premiere Pro.
