Hello
I’m having the same problem with masks merging.
What I’m trying to do is a text layer auto-traced or outlined and then merged all the masks made from the characters merged to only one mask to be used in radio waves plug-in.
I tried your method of copy them and paste it to a new layer and pre-composed, and then auto-trace, but I end up with the same amount of masks.
I even tried to make a layer in photoshop and import it so see if makes a difference, but no success until now.
Do you have any clues?
thanks in advance
Hugo
