Missing VRayRenderID xml report

V-Ray V-Ray for 3ds Max General
1

HI,
When I using 3ds Max to render with Render Elements, I can get a report XML for VrayRenderID. However, when exporting the vrscene and rendering it, the corresponding XML is missing.
How can I get the report XML for VrayRenderID when rendering with a vrscene file?
Or does anyone have another way to get RenderId and color value map

Thanks for the report. Logged (internal bug-tracker id: VMAX-14361) for dev investigation. I’ll ask the devs if there’s a way to workaround this.

EDIT: Sorry to say, there’s no workaround - the functionality is implemented only in 3ds Max.
