GIMP+Blender plugin bundle to export transparent images from GIMP layers to Blender curves as outlines. This is useful to create complex 2D shapes in Blender that are tedious to create manually. For example, you can create a mesh for a drawn character and animate it with armature or shape keys.
Blender 2.9x and GIMP 2.10+ required.
Install gimp_layer_to_curve.py in Blender preferences.
Copy layer_to_blender_curve.py to GIMP plugins directory (C:\Users\<user>\AppData\Roaming\GIMP\2.10\plug-ins under Windows).
Plugin will be available in Layer -> To Blender curve menu in GIMP. There's nothing to be done on Blender side, it works automatically via XML-RPC protocol.
