I just installed V-Ray 3 today and been doing some test rendering of old jobs that were rendered with V-Ray 2, too compare and see if there were anything different. It seems if you have an object with normals facing the wrong way and Multi/Sub Object material applied. The Object will rendered black. Force 2 sided is turned on, Tested force back face culling.
I tested it on 3 different machines and got the same results. I created a Box and Light source. Put a Normal modifier on the box. Created two materials one a Multi/sub w materials in every slot and the other just a standard material. Place Multi/Sub on box, hit render everything is fine. Check flip normals, box turns black. Put the single material on, box renders with material.
Is there a fix for this, other than fixing sloppy modeling.
Sorry if this is a re-post, I search and nothing came up that applied
