Since Photoshop compositing uses black and white masks for isolation, you’ll want to set your object of interest with a white wire color. VRay essentially picks this color for displaying the objects in the render pass. The wire color is the same one used by 3ds Max in the Command Panel. Otherwise you can select all the object pieces and assign the wire color. Now to create this render pass, it’ll be easier if your object is a single mesh. Moreover, VRayWireColor renders include the Depth of Field effect in the mask as well. This keeps the edges smooth and accurate. While both create isolation masks, the VRayWireColor element is more intuitive and retains Edge Anti-Aliasing.

The VRay Render ID and the VRay Wire Color render elements. More specifically, there are 2 render elements to choose from. While rendering with VRay you can choose to create such masks for Photoshop using the Render Elements rendering section. With the freedom of editing a specific object in an image gives you ultimate control and variation.

This is accomplished by using black and white mask layers that give you individual control over image elements. And one of the most valuable feature while processing images in Photoshop is the ability to Isolate Elements. By taking advantage of the post processing abilities they offer, you can reimagine your renders easily. Render Elements are one of the best features of biased rendering engines like V-Ray.
