Crop doesnt work with VFB render region

V-Ray for 3ds Max V-Ray for 3ds Max :: Issues
1

I noticed that when I use the the VFB render region, choosing the rendering region with the red square, Vray will revert to the original rendering size, ignoring 3DSMax crop settings and thus rendering in a different region that I wanted to select in the framebuffer. which makes either crop or the VFB render region unusable without cumbersome readjustments every time I switch between the two. I would like to use the vray render region along with 3DS Max crop … and I think it was possible at some point in the past..

I am on Vray 3.05.07

No, it was never possible. The VFB region essentially replaces the 3ds Max “region” mode. They are not applied together.

I’ve run into several situations where it would have been nice if they worked together. Any chance of having that feature in the future?

I see.

Here is a workflow that I will often encounter:

I have my camera film size and within that a safe frame in which my clients decides his composition. Sometimes we need more of that frame, sometimes less. And so in the end I only render out a crop. Since we work on that crop in Photoshop it is essential to always have the same rendering size so to be able to just drag the rendered image and have it in place.
But of course sometimes I need to test some smaller sections within that crop and for that I would like to use the VFB render region. I dont have the option to change the 3DSMax crop settings because of the drag-and-drop condition I described. But always rendering the whole image is a waste of time and resources and using the whole view in 3DSMax and then just using VFB render region is also a waste, because I wouldnt need the whole view in the first place and there is no option to save the VFB render region, is there?

I hope you understand the workflow and maybe you can adress it?

You could do that with texture-render mask instead of region render - just paint a quick black and white mask in photoshop and load it as a render mask.

That’s indeed a good workaround. BUt it’s also that. A workaround. :slight_smile:

Good point! Thanks for the reminder of the new features :wink: I will do that from now on.
BUT I have to say just drawing the render region in the VFB would be most convenient. Or maybe include the texture-render-mask into the VFB? That would be fabulous!
Shall I write a feature request for that?

Yes you could do that in Wishlist section:
