3DS Max - V Ray - VRayRenderID + Photoshop
Date Updated:
10/19/2023 In this tutorial, we will learn about the VRayRenderID render element, where you can create a separate file for the rendered image, and this file will contain a distinct matte color for each object in the scene. This is useful when doing a post-production in software like Photoshop, for example, because you can isolate every single object, and work on it separately.

V-RayRenderID
The word Lossy is not the accurate one here. The Issue with V-RayRenderID is that it doesn't do the Anti-Alias thing, so your rendered image contains Anti-Alias but the mask does not. Upon selection in Photoshop, you might end up with some ghosting on the edges. So, yes it has this issue, but it's the easiest to set, and you can be sure that all objects have a distinct matte color. I generally keep it in addition to other masks in case I forget to include some objects in those other masking tools, spacially in a huge complex scenes these things happen a lot.
Also, and in addition to all that, this is a tutorial and not a promotion for a feature. I made previously a tutorial about VrayCryptomatte, and I'm planing to make other tutorials related to render elements.
RenderID for masking is a bad idea...
V-RayRenderID is not lossy, meaning there is a lot of pixelization around the edges. V-RayWireColor is a MUCH better way to do the same thing! And for best output, MultiMatteElement is the BEST way to create masks.
