Hello @123456_1

I have tested the feature with latest Stable build and it seems to work. Please, install it and let me know how it goes: Chaos

Please, refer to the video-recording: http://ftp.chaosgroup.com/support/scenes/Cinema\_4D\_2023-08-02\_08-07-22.mp4

Your video added both objects as selection areas, so changing the color will definitely affect both of them. You can take a look at the project I uploaded. When I checked the Multi Matte channel, the selection area was bright, but when I displayed the color palette mask, the selection area became dark. Therefore, it is impossible to modify the refraction and reflection parts. Normally, these two masks should look the same, not one should be bright and the other dark
