Scene made in Vray 5.20.02 and RC 4.2.1 under 3dsmax 2021.3.2 and rendering via DR.
All workstations and all render nodes have equal access privileges to the NAS share vis SMB3 and a 10gbe connection.
Attached a screenshot of a small fragment of the scene.
There are vraylights behind the windows. Infront of every vraylight there is a curtain that is generated by RC.
The materical for the RC object is a simple vray material with a VrayMultiSubTex in the diffuse slot and a VrayColor in the opacity slot.
Locally it renders correctly.
As soon as I DR, buckets are all over the place and the material is being ignored from the DR.
BUT, If I disable the "Use Instancing Engine" in that RC everything renders correctly with DR.
Anyone else came across this annoyance?
