That does seem reasonable. As I'm not one of the cool kids with KHR access, mind letting me know what that bug says about what to do when someone binds both "array" and "array[0]"? Right now we store these in a map, and resolve locations at link time (as per the spec). We don't know what's an array and what's not at bind time. Also, does the bug make any comments about AoA? i.e. out vec4 foo[2][2][2] Should you be able to bind with "foo[0][0][0]"? What about "foo[0][0]" and "foo[0]" in that case? [Perhaps the AoA spec says something about this, I'm not up on all the details myself.]</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>
