Matte Viewer In the Gmask tracer


I’m a bit confused. I remembered looking at one Logik live but forgot which one.
In this episode, He/Her shows us how to connect the matte viewer to the camera to see and modify our alpha connected to the motion vector pass.

Does someone remember which live it was or can show me the schematic?

Thank you :slightly_smiling_face:

Forgive me Im not at my machine right now, but see if the Matchbox shader SelectiveMatteExtraction in the root of your /shaders directory is the one you are after.

Hello Randy, Can you explain how you use this node and what is it use for ?

Good news I found the live it’s the 26 with Christophe Zapletal around 27 min. (very nice one )

Make sure to look at the Comp Output

Amazing for roto in the tracer with motion vectors or for beauty work.
