.vismat Materials crashing Maya 2018.3 on render 3.6.004 osx

[paco_higham]

I've been having a problem using .vismat materials. When I use a Vray VRmat MTL, it will let me import the texture and everything will be good. However, it won't show up in the material viewer preview and as soon as I try to render (either IPR or Render) Maya crashes. I don't have this problem with .vrmat. I have a large collection of .vismat materials that I'd like to be able to use.

Thanks,

paco

HI,
it might be material specific crash. Does it happen with all the vismats that you have or only with some specific vismat materials? Also If possible sharing one of those crashing materials would be great for us to be able to reproduce and fix the crash.
Thank you for your feedback.

Thanks, Ivan. So far it's all vismat files that I try to use. Here's the first one that I encountered.

Also, if I try to render out an animation with a .vismat file in the scene, it will crash on the second frame every time.

I confirm the crashing with the animation and logged it on our system. However I wasn't able to reproduce the first crash. Is the first crash also a Fatal error crash and does it happen on simple scene? Can you send as a log from the crash so we can try to identify it?

[paco_higham]

Yes. It was happening on a scene that contained a single cube. I've attached the crash log.

W've found the other crash too. It seems that it was a known issue and is in our to do list. I'll let you know when it is fixed.
