R500 supports the same, and if the back-face colors are unused and flat shading is disabled, it reuses unused color outputs as generic varyings, so that it can do 10 generic varyings. In addition to that, the GLSL compiler implements varying packing, but it's only enabled if the number of supported texture indirections is greater than 8. Therefore, R500 gets the varying packing, but R300 and R400 don't, which can do only 4 texture indirections. However, this can be easily fixed in the trapezoid shader by combining the float varyings into vec4s. Each float occupies the entire generic slot as if it was vec4.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
