This is certainly not a high-priority request, but something that would be handy.
All the time you see people posting with requests to try and figure out problems with their render settings. Some end up typing a few settings in shorthand. The more adventurous stitch and post an image of all the rollouts. It would be slick if there were a button to export txt or xml or something right from vray and include it quoted as code with our thread.
Ah, no. In the VRay System rollout, there is a button, Presets… It allows you to save selected settings into a text file (the file is written in the Presets dialog).
