This is more of a workflow question than anything else, I was going to do some logo animation from a layered PSD. Import PSD doesnt seem to work correctly currently, so to work around that I thought I would import the logo as a flat image with an alpha channel, then separate it using polygon masks.
So I guess really I kind of want the 1 loader, splitting off into as many streams as i need each masking out the various section I want, then a transform node on each stream that I can animate, then merge them all back together again.
The difficulty I'm having is the mask nodes don't seem to actually work 'inline' on a stream, but are used to mask another node that is on the stream? What kind of node would I use just to set alpha to 0 and premultiply if necessary? Or is there an equivalent to the 'Roto' node in Nuke that you can draw a shape and set it to black alpha, inline on the stream? I tried a channelBoolean with 'to alpha' set to black, but the results are wierd, the stuff inside the mask seems to go partially transparent or something when merged over anything other than black?
I may have also found a bug, in the default view layout - you can select a node, and click the little mask icons on the viewer, and it will add a mask to that node. On any other view layout however, the buttons, they do nothing! (you just click and no node appears)
Also getting a lot of fusion crashing to desktop scrubbing some alembic files here, seems if I scrub quickly back and forth, boom, fusion disappears.
