Hi there,
I wrote to the nuke-list but I think my question is better placed here.
I would like to use the PointPosition/WorldSpaceCoordinates -Pass to
stick a custom Roto-Mask to non-moving objects
My idea is to use a 3DLut to colorcorrect the PointPosition Pass so I
got my mask sit in every frame.
I have normalized the PointPosition pass - so that the range fits the
CMSTestpattern ones.
what now has to be done is to set the CMSTestpattern color values to
the corresponding mask values at the positionPass xyz values.
I think it has to be some kind of a keyer.
Is that possible with the "Expression" oder the "Merge Expression" node?
or is there a way to do that with python?
I hope I am not to confusing
cheers,
Vincent
