I'm quite new to C-2 so there might also be something in the manual (the one that came with the program) that I've missed. the problem is that a texture map that I've mapped on my vertex object with cylindrical mapping mode won't stick on the object as I try to animate the object with bones. As the object moves the material stays where the object was originally located disappearing as it is left behind.

I haven't played that much with bones, but it might help if you set the mapping mode in the vertex modeler to cylindrical, and change the shader to the standard Multi Channel or Parametric. If the mapping mode is set in the shader it is going to ignore the changes in geometry of the object, and still try to map it in a cylindrical aligned with whatever axis, instead of a bent cylindrical. Setting the mapping mode in the VM doesn't work as well if it is a low poly model. The other possibility is to make a UV map with the UVMapper (that comes with the CD), which takes a little playing with, but has great results.

Thanks for the advice. I hadn't noticed the UVMapper on the CD. Although it didn't do much good this time I now know how to get more shader domains on my vertex models. I finally chose to set up the custom UVmapping from the VM and using the parametric mapping mode. It seems to do the trick. Even with a lowpoly model.
