3.3 vs 2.9 - Now Similar Colors for Different Materials & Objects in Render Passes

3.3 is behaving differently for me than 2.9 regarding Material ID and Object ID passes.

In 2.9 Object ID passes showed different colors for each object. In 3.3 instances appear to be the same color.

In 2.9 Material ID passes seemed to be randomized between different sessions. That behavior is now different, where the colors seem to be consistent between sessions.

However, in 3.3 colors being used for different materials… in my leaves on different trees with different materials… are now being rendered VERY similarly to each other. (Slightly different shades of green)

It is almost as if the Material ID pass is now following some new rules.

Anyone else experiencing this?

Thanks!
