Combustion - masking operators

[Tim Nelson]

Say I have a footage layer, and I apply a color correct operator to it. Is there a way to select a mask that will allow me to only use the color correct operator on the masked area? And then I would like to be able to do that several times to different parts of my base footage. Sort of how in Photoshop you can have a main layer with lots of adjustment layers & masks on top of it.

 

I know I could copy the layer a bunch of times and them do a 'set matte' for each channel I want to work on, but I'm worried that would lead to too many layers and too much memory usage.

 

Any suggestions? I know you Combustion pro's are out there. Thanks
