I simply manually unrolled a loop and turned a function into a macro. There are no functional differences and these changes should make no difference in the resulting code, yet they make the shader work. I don't know why it works and I am not an expert in this stuff, but I think there could be a bug in the GLSL compiler. Maybe the register allocator messes something up and manually unrolling the loop fixes it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
