V-Ray V-Ray for Maya General

Hi,

Is it possible to render a point position pass in vray to use in conjunction with a normals pass in nuke to relight an object?

Thanks

Chris

Yes, just use a VRayExtraTex element connected to the position output of a SamplerInfo texture.

would that be the pointObj output fro msamplerInfo into the vray_texture_extratex r,g,b ?

doesnt seem to be a position output.

Thanks

You need the “pointWorld” output of the samplerInfo connected to the “vray_texture_extratex” input of the render element.

Is there a way to save custom render elements?

You mean save it as a preset? Or you mean the output image?

Best regards,
