In V-Ray GPU CUDA, if you make a specific hierarchical object invisible from the camera with V-RayObjectProperties, the material of the object will not be reflected correctly. Confirmed by V-Ray 5 C4d, update 1.2 (v5.10.22) Attach sample scene ![2021-09-14_232551.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/d/8/d8b5d39f9b8bc0e44e076dc6b70a46218697f2e1.jpeg) [test.zip](https://forums.chaos.com/uploads/short-url/trXnJKohiaJyjeCdyCWU8bNQqo7.zip) (87.9 KB) ---

It’s actually seen in the reflections. The bug appears to be on how the materials are assigned. If you leave have multiple materials in the hierarchy, it’s using the last material on all of the items. Seems like the bug is related to having multiple objects in hierarchy with different materials PER 1 Object tag. Only when rendering w/ GPU ![bug.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/3/6/361b5fc9f715a2e114ec2468c43ccce813e08549.jpeg) ---

Yes. The solution is to assign the material individually to the object instead of Null. However, there is a problem with the behavior of material allocation to Null different on CPU and GPU. I hope it will be fixed. ---

Hello, This seems to be the same issue as the one, described in this [forum thread](https://forums.chaosgroup.com/forum/v-ray-for-cinema-4d/v-ray-for-cinema-4d-issues/1108558-the-vray-object-properties-tag-doesn-t-work-on-a-hierarchy-gpu-renderer). I’ve already reported it to our developers (bug ID: VC4D-882) and I will let you know once we have more information. Thanks. ---
