It would be great if you could load in a black and white map jpeg sequence (or an PNG with unpremult alpha) to act as a custom render region. So if you need to re-render just one element in your shot you can isolate it and do it quickly. Thanks

It would be cool to have junk mattes similar to the polygon region render but applied to the vrimage as a post effect. If you could add them as another MM similar to how you can add or subtract multiple MM currently. For photoshop users, VFB is th...

Cosmos has animated trees now, but they can only be used with Vantage. I never have a need for a real time renderer, but instead often render out animation for use in video. I would really like to see these animated trees compatible with Scatter a...

Many architects export rendered elements such as shadows, lighting or occlusions to use as underlays and overlays with linework. However, VRay only exports these with a black background. For example, if you wish to use these rendered elements unde...

It would be nice if there was a possibility to save workspaces (like in Adobe Photoshop, etc.). For example, I'd like to save the render window in a specific size on my second monitor. And it would be nice to be able to have the main V-Ray window ...

Nuke has this feature, using Z channel data for refocusing. I hope VRay VFB can do the same.
