Rollover image to view Object ID object_id pass (Utility utility shader set to 'obj')
The aov_write shader in combination with the utility shader is a useful combination for writing out an Object ID pass. This simple setup will allow you to use an ID pass in compositing software to identify certain objects by their color. We will also isolate certain objects and give them specific id's with which to group by color.
- Open the Slate Material Editor.
