The VideScape format does not support texture definitions but this does not prevent you from defining new surface attributes for the object once it is loaded into LightWave. >What happens is thaat each polygon gets mapped individually instead of each >being treated as part of a surface.

This is not true. I'm am not sure what you might be doing wrong but I have no problem assigning 3D procedural textures to the surfaces of VideoScape and Sculpt objects. These surfaces work just like any other Lightwave surface except for the fact that when they are imported in, they automatically load 2 polygons for each one specified (for front and back sides) so that back face culling won't inadvertantly delete a front facing surface. As for the LightWave file format, as a beta-tester, I have a hard copy of the 3D format specification , but I don't think it has been publicly released other than to a few developers. You would have to contact NewTek. %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% % ` ' Mark Thompson CONCURRENT COMPUTER % % --==* RADIANT *==-- mark@westford.ccur.com Principal Graphics % % ' Image ` ...!uunet!masscomp!mark Hardware Architect % % Productions (508)392-2480 (603)424-1829 & General Nuisance % % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
