Support
As other support issues are raised, I will list them here.

Textures
The biggest suport issue seems to be textures, Sketchup stores the path to the location where the texture was when it was created in the file, and if the texture is no longer there, you need to export the texture out of sketchup so POV-Ray can find it.

The Mac version of SU2POV assumes you duplicate the colors in the model to export the textures as tif files. If you need help with this or more information I have a specialist page on textures here.

Xgrid
Xgrid is still in beta, I do not expect Xgrid will be much use until SU2POV exports animations.
