I have posted a few times, read forums and haven't sorted this out!
I am trying to displace a group of poly's on a sphere using vray displacement modifier. I can get both 2d and 3d displacement working on simple primitives such as on a plane (for 2d) or a box (for 3d) where the geometry is unchanged. As soon as I try and get displacement working for a group of poly's on an editable mesh object I have no joy at all! I get the warning "can't displace mesh, map channel 1 not supported" All I am trying to do is select a group of poly's on the side of a sphere and displace them to the shape of a displacement map I made in photoshop.
I also noticed that when I displaced a plane with a uniform mesh the bitmap showed up perfectly, however if I moved some of the edges to make them squint but kept the plane perfectly flat, the bitmap showed up changed as well (skewed). The reason I ask "should this happen" is because how can you displace poly's with a bitmap and have the bitmap show perfectly undistorted, if the group of poly's you are selecting have been moved around (say to form a curve, rather than being a plane?)
Can anyone who has successfully managed to do this tell HOW IT IS DONE? as all the tutorials I can find describe simple mapping of planes and 3d objects ro make stuff like hedges or billboard posters!
Thanks
