I went ahead and purchased the studio version.This program was well worth it.
I have to admit it has a funny activation method though.One file you place in your My Documents folder.
Works though!
This program loads well with Shellout also - just export with the script - load your texture - load the tempfile as a buffer and click generate.You will have to locate the temp file first at
C:\documents and settings\userName\local settings\shelloutTempFile.png
Or wherever gimp saves yours after exporting.
I'm having a blast with this program!
