Auto-Bake is a graph-specific option that keeps affected Blender images up to date as graph processing produces newer results. For a new setup, first configure Outputs, run Bake to Blender once, create or update the Blender material if needed, and then enable Auto-Bake.
Auto-Bake respects Include in Bake/Export and uses WonderTexture’s incremental graph updates, so only affected enabled Output branches need to be refreshed. If an Output is disabled, its existing Blender image is kept at the last baked version instead of being deleted.
Auto-Bake updates image pixels, not material structure. If you add a new Output such as Roughness or Height, run Create / Update Material so the shader gets the new connection. External files are still written only through Export Files.
AUTO-BAKE OR MANUAL?
Use Auto-Bake when Blender images should follow graph edits automatically. Leave it off when you want Bake to Blender to remain a deliberate production checkpoint.
