Render Node command line, the render results don't contain idmap.png

Is there command for control the render result, If just use vray.exe -sceneFile=“xxxx.vrscene” -imgFile=“xxxx”, There is not idMap.png, what I can do to have idMap.png

Hi, thanks for posting. Could explain a bit further what is “idMap.png”? Is this s render element that you are trying to save?
