Crash when using Double Switch and Rect Light

[stevegh]

Say you want to have the same texture in 2 lights but you want the UVs to be flipped on one of the lights. On a plane you could do this with a double switch in the place 2d texture, but if you try to add a vray light to the input list it crashes Maya. Is this something that could be fixed or perhaps the workaround is to use mesh lights?

Can you post a scene?

Sure.

Attached is a screenshot of how it works with normal Maya nodes. The documentation can be found here.



Try adding the ramp to the texture slot of two V-Ray rect lights (or even a mesh light), and middle mouse drag them into the double switch inputs to see the crash. Trying to rebuild the network from scratch yields the same result.

Thanks for the details - we managed to reproduce the crash.
We'll add it into our system and we'll let you know when it is fixed.

The same crash actually happens with any Maya Light.

Most likely light nodes are not supported.
According to Maya Docs, isShape node supports Shape-nodes but it is not specified whether it supports Light-Shape-nodes or only Surface-Shape-nodes.

Ah, well chalk up one more thing about Maya I love! Thanks for tracking that down.
