Standalone command line options for "Ray Bundle Size" and "Rays per Pixel"

This is more a feature request for the core-team, but it’s affects mainly for the ones using V-Ray standalone together with V-Ray RT GPU. The Ray Bundle Size as well as the Rays per Pixel are written into the .vrscene during export and have to modified manually by using a text-editor if you need to change the values. Different values are needed if you use V-Ray GPU for preview purposes, final-frame rendering or using distributed rendering. So it’s a constant changing of these settings depending, and you end up having to re-export (or edit) your .vrscenes everytime you forget to change them, otherwise you’ll loose a lot of performance of your GPU

Hello,

You can already do that. V-Ray standalone has a parameter “parameterOverride” and with it you can override any value in the .vrscene file.
So for example to change the ray bundle size and rays per pixel you could use the following command:

vray -parameterOverride="SettingsRTEngine::gpu_samples_per_pixel=16" -parameterOverride="SettingsRTEngine::gpu_bundle_size=192" -sceneFile="your.vrscene"

Also if you start vray standalone without any parameters it will print the available options. There is some more info about parameterOverride in there.

Best regards,
Yavor

Thanks for that, So no need to manually edit the .vrscene. Great. You just have to find out, how the parameters that you want to override are labeled within the .vrscene-file
Now I just need @vladimir.nedev to add this options to the “Render with V-Ray Standalone” dialog
