(0002167 - 55 - 67 - 67 - 67 - 67 - 67) elenzil 08-05-05 20:44	any thoughts on this one ? 8 lights is sort of few.

(0002168 - 227 - 239 - 239 - 239 - 239 - 239) Croqueteer 08-05-05 20:59	OpenGL typically maxes out at 8 lights. However, I wrote some code that should have managed this properly and eased additional lights in and out depending upon observer distance. Evidently, this is not working (anymore). DAS

(0002336 - 168 - 168 - 168 - 168 - 168 - 168) bert 08-14-05 21:42	As David said, we should not enable more lights than GL supports. However, this should not crash - report this to ATI. Also, someone should try this on an NVIDIA board.
