Mask Effect problems - doesn't work in runtime?

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.

Can you link to the .cap file?

Of course ^^;

Sorry I thought I may have been missing something normal so didn't consider needing to share the .cap in first post.

Here you are - ifile.it/9v1sb6e/treemask.cap

I don't know why it doesn't work. I think I did the same thing and it worked for me.

Thanks a lot for that example, I wouldn't have suspected it at all but

for some reason the actual sprite in that scene wouldn't work with erase,

however copying it and pasting a clone allowed it to work....might be

something to do how it was created in an earlier version, somehow?

I created a new scene and made a test like your own and it worked perfectly,

before going back to that tree file and discovering that issue.

Anyway, thanks to your help I've got what I wanted working in my project,

so thank you very much for your time and help :)!
