This is a minor request, but it would be nice if the material 'scripts' used the same order of images while exporting alpha maps.
I am currently trying to load all *_000.xml files in a directory and generate a list of alphamaps from that, but the order is not always the same.
I know I could just use std::sort (or similar) to make sure the entries are sorted equally, but it would save me from either doing that or manually editing the files.
I already have some logic in code where I insert a blank alpha for pages with less than max textures (because my terrain engine requires an equal amount of texture layers, and some pages uses only one or two textures, instead of three).
So, and option to generate blank alpha-image entries would also be appreciated.

A minor issue, though.
