Eric: Thank you for your speedy reply. I can see the problems faced with mapping IFF files onto an object and keeping the interface simple. Your idea about hooks for defining textures would be very handy. That would free SCULPT 3-D from having them resident. Also, in regards to painting details directly onto each polygonal face, I believe that a fairly effective and easy way is possible. Let me try to explain this: Naturally each polygonal face would be presented to you in 2D. Instead of painting an image onto the face why not supply an IFF file or brush for the design? The IFF file could be scrolled behind the polgonal face (which would act as a window of that face shape) and the desired portion of the IFF picture can be selected. I believe that this would be keeping on the 'Ease of Use Interface' track that SCULPT 3-D now has. In terms of contour mapping: It would be usefull to be able to map an IFF file onto a sphere for example. The edge of the IFF pic can be alligned with a longitude line on the sphere. The mapping can be then done. If the camera view coords. change then the new 'mapped view' of the sphere can be recalculated. Since the allignment is still available to the program, this can be easily done, thus keeping an easy to use user interface. Hope I got my ideas across well and forgive this long winded message.
