I actually have the original image as a vector based CorelXara image which can
be converted to CorelDraw easily enough. Can I use this in a 3D modelling
program and 'extrude' it somehow? That way I can avoid using bitmaps and
height fields etc. When I use a very high quality bitmap the file takes ages
to parse. This is a pain for animation type stuff because it happens for every
frame.

Cheers

Mike
