Apparently a lot of users are confused about the new RenderOutputVRay in renderStacks 1.222. To prevent the confusion. We added explicit “V-Ray saw image file” checkbox so you can turn off V-Ray raw image file output when you don’t use multi channel exr.
Also the documentation has been updated for RenderOutputVRay. Please read the documentation!
Also there is another changes. Please check Change Log for details and other changes.
