"Pre-Multiply/ Matte with color" Question?

[macool]

I have some CG car renderings of the Car rendered on a white background (including an Alpha.) I’m getting some nasty white edges. I realize I can matte/dilate or chew this…however

I was wondering if anyone knows how to “pre-multiply-matted with color” a CG with white and black and or values of grey in FUSION;… kinda’ like the way you do this in After Effects Interpret footage?

thank you

All the color correctors in Fusion have a predevide/post multiple option, this will clear out the white Bg.

The better way is to a Matte Tool and use the Post Multiply Image option.
This tool can be used to blur and expand or contract the alpha as well.
