div0 said " the shader is used like this: uncomment FRAGMENT_SHADER that is the one that crashes uncomment ONE of the modes I'd suggest MODE_LIGHTDIRECTIONMAP_MODELSPACE and uncomment USEDIFFUSE, USEGLOW, USESPECULAR then you get the basic shader that's used for most surfaces in the game and that sure is one of those that crashes when I had tested it, it also crashed in just MODE_LIGHTMAP (which is used if deluxemapping is 0) " the code is in attachment. I hope this will help. <div class="gmail_quote">2008/10/28 Eric Anholt <<a href="mailto:eric@anholt.net">eric@anholt.net</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Right now most GLSL debugging on the 965 driver is on hold while idr rewrites Mesa's GLSL compiler, since the driver part will need to be mostly rewritten after that, anyway. However, if people could isolate failing shaders and get them into piglit testcases, we might be able to get to them earlier, and it would benefit all future GLSL work as well. </blockquote></div>
