Object Properties with Matte Surface generating different render element between vrscene and maya geo

V-Ray V-Ray for Maya Issues
1

Hey there,
I was using VRayObjectProperties to create Matte surface for my render layers, and I noticed that GI and Lighting pass are not black on my matte surface.
I quickly create a simple scene, and realize that this only happen when using vrayscene as matte surface. If my matte surface is a Maya Geo, it’s all black in all render elements.
I am using Maya 2023 and VRay v6.00.03, is there something I need to check to make matte surface not showing in GI pass while using vrscene?

This a simple scene I created with a cube and a ground plane. The ground plane is in VRayProperties set with Matte Surface on

you can see on the left , a Maya geo plane, it’s all black in GI pass,
But on the right, it produces GI on matte surface using vrscene( I tried loading both vrscene and usd file).

This issue seems to be fixed in the latest official build. Update and try again.

Thanks!
We are in the middle of a production, so I can’t just update now. But I will definitely give it a try after.

Best,
