This add-on provides a bi-directional live link between Blender and Substance Painter, streamlining the exchange of 3D models and PBR materials. It allows users to send geometry, including rigged meshes with active armatures, directly to Substance Painter without applying modifiers. The tool supports multi-material setups, ensuring individual objects retain separate texture sets during the painting process.

Users can choose between manual synchronization or a smart auto-sync timer that automatically pushes geometry updates and texture changes across applications. The add-on features an additive export system to introduce new objects to an existing Substance Painter project, and includes a dedicated scene panel within Blender to manage exported assets.
