Multi Mattes behaving weird- not 100% R,G,B...

Hi,

Been having strange behavior with multi mattes- they are not pure 100% Red Green or Blue, instead of being 255 it’s at 205 (grey) and it seems to be picking up reflections? I feel like this could be useful in certain situations but not for 99% of the time.

There’s only like 1 attribute for multi mattes… what am I missing?

Thanks in advance, look forward to having normal multi mattes again soon :smile:

in the shader of the car paint make sure the reflection is not contributing to multimatte I think its called affect channels it should be set to color only not all.

Awesome thank you!!!
