Slow to kill

[glorybound]

I am running the latest V-Ray with 3DS MAX 2015. Nothing special with my scene, however, all of a sudden it is taking 3-4 minutes to cancel a render. Typically, I cancel during the LC pass and usually it isn't an issue.

more like 7-8 minutes to kill.... WTH!

displacement?

Yep! When I globally disable it then the slow to kill goes away.

Actually, it was a Walls & Tiles shader that was causing havoc. I had to rebuild it. I won't get this 1/2 day back!

I have similar issues with W&T shaders.
Especially after I upgraded to W&T 1.4. Probably something with the new licensing system.
I installed both Floating License and a Node-Locked license and unfortunately W&T 1.4 performs bad and slow.

After a long troubleshooting with VIZPARK support and trying out 1.4.1 beta and "special builds" of 1.4 I ended up installing 1.3.2 on Max 2016.
So far so good.
Now waiting for a proper 1.4
