This is just a zipped version of the BAU-Tools, because the RAR-Archive of my former upload could only be decompressed by Winrar 3.1 BETA
The BAU-Tools allow you to automatically unwrap a polygon mesh quite exactly how YOU want it.
So you define CUT-Edges direcly in your 3dView, along which the created UVSet will be separated.
You are even able to create "Control-Zones" that will manipulate the flow of the UVSet created by the script.
Slight errors can perhaps be corrected with the SoftselectionTools, which make soft transitions easy to achieve (although they are quite slow :( ).
All these (and more) features are packed into a workflowfriendly GUI, and full DOCs (including Quickstart-Tutorials and detailled Descriptions) will make it easy to learn and get nice results.
Features:
• Userdefined Automatic UV-Creation
• Integrated UVSet-Editing
• Face-Include/Exclude
• Create high-priority Faces that will act as a group(-->Control Zones)
