Render issue with Asset "Lamp Table 009"

[aida]

I've got some strange render issues with the asset Lamp Table 009.
Some buckets get stuck and adaptive bucket splitting doesn't take place. The render won't finish. It seems to be the sub material Plastic_01_mtl which causes the problem.
But only in light environments. (?) I've got a scene with a dome light and a VrayPlane with a light Vray Material. When I assign a dark grey material to the plane the scene renders fine (including adaptive bucket splitting).
We're on Max 2023.3 with Vray 5 Update 2.3

Could someone confirm and fix the issue? Took me some hours of investigation to identify the buggy asset.

Hi, thanks for posting. I tested the model in a simple scene with a dome light and a camera and there is indeed something strange happening. Let us investigate a bit further and we will get back to you.
