This is not entirely my result. Node setup is very much inspired by
http://www.blendswap.com/blends/view/67519. This lady is procedural.
just wondering if it should be possible to pack the masks a little by storing information of three regions in the r g and b channels in one mask.
Of course, but that's not the issue. PNG does well when it comes to lossless compression. Even if it wouldn't, space on harddisk is not the bottleneck. Available RAM probably is when using GPU rendering.
Of course it only works for masks, that do not overlap.
Why? RGB images store three independent BW images in one file. The R channel is in no way influenced by an overlapping B channel. You shouldn't try to save such an image as JPEG, of course. But as already stated: It's not the issue. However these maps are stored, they need to be unpacked into RAM.
