In 2.9 objects with a material that uses a MASK texture showed up correctly in Material ID and Object ID passes.
In 3.3 & 3.2 objects with a material that uses a CUTOUT texture show up incorrectly in Material ID and Object ID passes.
Note: This likely may affect 3.0 & 3.1, I switched directly to 3.2 from 2.9. (I was avoiding the upgrade because of all the issues. We can add this one to the list. )
See attached.
Thanks!
