>>but can this method be used on not just >>shiny objects but on refective objecs as well?? Well, the routine just looks through the rendered frame pixel by pixel. If a pixel's luminance (brightness) exceeds the threshold set in the IXP dialog, the HILITE IXP will paint a highlight at that location. Hilite.IXP (and any IXP created thus far) doesn't care what's in the 3D Scene or what the materials are because it only looks at the pixel RGB values. I've heard that R4 allows the IXP routines to access the Z-buffer data, so new IXP IPAS routines may interact more with 3D aspects of a scene in the future. Jim
