BlendSync is a Blender add-on built by Mangoframes for moving assets between Blender, Unreal Engine and Substance Painter, and bringing them back into Blender. It covers the round-trip that the name describes, connecting three tools used in asset creation.
Distributed as a Blender extension, BlendSync is compatible with Blender 4.4 through 5.1 and works with both the Cycles and Eevee render engines. It is released under the MIT license. The add-on has recorded over 100 sales and holds a rating of 4 from five reviews.
Mangoframes includes documentation with the add-on, along with support and product updates. A demo video is available for anyone who wants to see more before installing. BlendSync earns its spot in the superhive library as a focused bridge between Blender, Unreal Engine and Substance Painter.
