External Paint Autorefresh
Addon that synchronizes Blender with GIMP and Photoshop for texture painting of 3d objects
External Paint Autorefresh is open source under the MIT license
Download: current version 3.4
Have you ever worked on a 3d model in Blender, and created a texture for it in GIMP or Photoshop? External Paint Autorefresh lets you texture paint in GIMP/Photoshop while the texture updates automatically in Blender, or switch to painting in Blender while the texture updates in your image editor. It also takes care of the UV layout and other similar layers in your image editor, ignoring them when saving and reloading the image.
Below is a list of features, and the manual has more info. For comments, bug reports, etc, please post them in the addon thread or send an email to firstname.lastname@example.org.
