Assigning materials BUG

[ANDREW_DECKER]

I'm encountering a bug when I assign materials. I like to assign materials by layers. The first time I assign a material to a layer it works just fine. The problem comes when I want to change the material assigned to that layer. It's not every time, but most of the time when I change the material I click the 'Browse' button and get the drop down menu, I scroll down to the new material I want to assign click okay and the new material name will appear in the Layer Materials box for a split second before switching back to the material that was previously assigned to that layer. I then have to go back through the browse button and assign the material I want again...and the second time it will stick with the new material I've assigned. It's a real PITA especially when I don't catch that it switched back and I render the wrong material.

This is a recent problem. I recently installed build VRayForRhino5x64_2.00_25584 and that was when I noticed the problem.

Any help would be appreciated.

Andrew,

Can you post a 3dm that causes this problem. If it is just one object, and two materials, that would be prefect.

attached 3dm file that exhibits the problem

Okay, with a little more investigation, I've discovered that with a super simple 3dm file with just 2 materials it doesn't happen. But there is no such thing in the real world anyway. I have attached a cat fountain that I've been working on that has been exhibiting the problem.

Andrew,

I looked into it, it appears to be a bug with Rhino. I'll work on an example to send to McNeel, and see if they can resolve it in the next service release. Until then you can you use the "Apply Material to Layer" in the V-Ray Material Editor context menu.
