You might try this trick to get it working. I noticed on a few occasions that it helped.:
1) Go to your MYDOCS/APPLINKS/3DCOAT/EXCHANGE folder and delete or move to a separate location, the BLENDER folder.
For some strange reason, the contents of that folder mess up the Applink once in a while.
2) Test a simple export of the default Cube in Blender, to 3DCoat and back
Script updated 1.61
- Supports 3d-coat -> Blender workflow
- New video tutorials
You can try this script version. With this it dosen't matter where you start. You can start your model in 3d-coat or blender.
I posted a new tutorial. There is no talk but they show the basic workflow. Hope it will solve the issues you have. But if dosen't, let me know.
