An interesting problems here. One I've never encountered before. Using an SGI PI, I was adding lighting to some code. What appears to be happening is that the machine itself is ignoring (or setting to zero) any Z component of any light. Which is to say, if I specify a light as front[] = {POSITION, 1.0, 0.0, 1.0, 0.0, LMNULL}; the machine treats it as: front[] = {POSITION, 1.0, 0.0, 0.0, 0.0, LMNULL}; You can see how this might get irrtating. It IGNORES the default light! Any light I put at any location outside the Z plain gets projected back to it! Any suggestions? +-------------------------------------+----------------------------------------+ | "When the going gets weird, | | | the weird turn pro." | Marc Cooper mcooper@cs.uiuc.edu | | | University of Illinois, C-U | | -Hunter S.
