In CS4 you have File > Scripts > Save Layers to Files works just fine. Can't you make an action that would create a new layer beneath each folder, run Apply Image, make all other layers invisible and run the Save Layers to Files script with the "Only visible layers" checked? Do you know what I'm getting at? :)
hmm I might use that as a base and build a quicker access panel instead (Flash movie, containing the Javascript) of the script menu thing. I saw thema year ago but kind of forgot about them.
Nice setup script ;) Yeah, Harl's vtools do exactly what you say for exporting. I actually made my own similar tools for work (with a few extra features and a whole lot less UI clutter!) but I don't think I can share them :(
Putting spec in alpha channel as pointed out means greyscale spec also means pain in the ass to edit, no layer support so you have to keep making edits to your spec elsewhere and then cutting pasting into the alpha channel. For me it's annoying As for the one map approach here are the downfalls I've encountered in that…
