TQ SubstanceLink is a Blender addon from Techqon core that links Blender with Substance Painter. It builds an organized folder structure for every Blender–Painter project, on local or cloud storage, and keeps Blender assets and materials permanently linked to their Substance Painter files. The connection holds even when Blender is closed, so changes made in Painter are reflected later.
The addon includes a live link for testing and prototyping: send a mesh to Substance Painter with one click, paint and export textures, and see immediate updates in Blender. You can create reusable materials and auto-send them to Painter for texturing, with saved materials appearing in Blender's Asset Browser. Asset projects manage high and low poly versions in unified folders, linking Substance projects to Blender objects.
Texture updates apply automatically, with a manual refresh option and a built-in Live Update system to keep scenes consistent across changes. Non-destructive editing lets you reopen a linked Substance Painter project anytime while Blender links and references remain intact. Categorized libraries support local and cloud storage such as Dropbox and Google Drive, and a recent version adds macOS support.
