I'm bit new to the Blender Applink. I tried briefly to test the Applink, but I didn't get it working. I'm running the latest Blender 2.91 and 3DCoat 4.9.67 (Trial Version) in Windows 10. I just used the default cube in Blender in my test. At the start the Applink asks for the Exchange folder and I set that up as "C:\Users\Firstname Lastname\Documents\3D-CoatV49\Exchange". When I hit "Send" from Applink (Per Pixel Painting), I get the mesh to 3DCoat. And then I paint quickly just something on the mesh. And then hit "File - Open in Original App" and disable the "Export Geometry", but leave the "Export textures " on, and then hit "Export". Then I move to Blender and I try the "GetBack", but I get the following error:
Python: Traceback (most recent call last):
File "C:\Program Files\Blender Foundation\Blender 2.91\2.91\scripts\addons\io_coat3D\__init__.py", line 235, in invoke
Export_folder = global_exchange_folder
NameError: name 'global_exchange_folder' is not defined
location: <unknown location>:-1
But I have checked that the "Exchange folder" is set on the Applink settings, so it should find it. For me the "Object/Texture folder" was empty originally, so I tried again to set that folder as "C:\Users\Firstname Lastname\Documents\3DC2Blender\ApplinkObjects", but no luck. Also I tried to save the mesh first in blender and then trying again, but no luck again. And also I emptied the ""C:\Users\Firstname Lastname\Documents\3D-CoatV49\Exchange" and "C:\Users\Firstname Lastname\Documents\3DC2Blender\ApplinkObjects" folders and then tried again, but still no luck.
