I tested your patch here on an Intel Mac and it works like I think it should work. Two of the layers are partially transparent based on the individual R G and B values. Can you post a screen capture of the working and non-working output?

hi,
I am finding that gem is doing things very differently in two versions. The attached patch is slightly simplified from what I am running but the essence is running 3 versions of the same movie on 3 'screens' using [pix_threshold] and [pix_alpha] to selectively hide elements of the pictures at the front. This works fine when I use pd-extended0.38 When I try it with pd-extended0.39 (from http://at.or.at/hans/pd/installers.html ) it doesn't work. The pictures on the front 'screens' are all turned blueish but the selections aren't removed. I am running this on an intel Mac OSX10.4 I would be happy to stick with 0.38 but other things aren't working correctly with it, and I can't even run two versions in parallel because hans' version handles libraries internally, and gets confused when there is a preference file like the older version wants :(
Any ideas?
Thanks Oded
