Greg! My savior!
I am quite ecstatic to inform you that after not giving up on your initial explanations I continued to attempt explaining to the Rotobrush exactly what I wanted from it.
What ended up working the best was simply this… I adjusted the size of the brush to that of a pixel. I would zoom in and literally draw on the pixels that I didn’t want to include in the matte and suddenly (sometimes after a single stroke, sometimes after multiple strokes) it started to see exactly where I was telling it not to go.
I just want to thank you for improving my work flow and giving me a new technique that I will surely use for years to come!
Best,
Eddie
