As I mentioned, merely having the ext available wouldn't make that shader compile. The ext would also have to be enabled in the shader. However perhaps the game would detect the availability of the ext and stick a "#extension GL_ARB_arrays_of_arrays: enable" into that shader, which would make it work -- no way of knowing that.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
