I've just started looking at the scripting possibilities to see if I could make a per layer mask option.
I'm not sure its possible, there is no proper blend modes (eg multiply) that I could use to mask one layer only.
do we have to wait for 3.0 to be able to make a module for this feature?
this is really important to me, if I can't do layer masks I can't use modul8 in most of the gigs I do (shaped screen clusters)
