I've been trying to get this mask/erase working for ages,
going through a lot of topics, but none seem to ever answer
the necessary questions.
Worked out though eventually that both images need to be on
the same layer, and you need 'force own texture' enabled.
This works fine, in the program area, however when you try
to run the application, it completely ignores it.
as seen here - (note: screenshot from someone elses downloaded test file)
Is there some setting somewhere else that's missing?
I'd really appreciate an answer for this.
