MtoA ‘non-rectangular quad light’?


#1

Hi there. So I’ve been playing with Arnold and found a weird error: non-rectangular quad light is not supported. I have Several aiAreaLights in a group, and when the group gets rotated in a particular manner, around all three axes, this error pop’s out and the render fails. I thought that it could be some shear going on, but I have checked all transforms in the hierarchy, and none of them has it, so it must be something else. The scale is also positive and not zero anywhere.

Any idea what might be the issue here?
