4. Mesh Maps Baker

A stand-alone baker for mesh maps, to disk, independent of the stack — for a mesh you want maps for outside Overpaint, or to bake a set of maps once and keep the files. It is above the main OP Painter panel.

Control	What it does
Texture name, Size	the file stem, and the size (the paint size, or 256–8192)
Device, Samples, Margin, Format	the Cycles device (GPU by default), 32 samples, 16 px margin, PNG or TIFF
Selected only	bake the selected meshes rather than every visible one
Maps	AO (with a distance), Curvature, Thickness and Edge (with a radius) on by default; Position, World Position and Normal off
High → Low (by name)	pairs name_high with name_low (the suffixes are editable), with a cage, cage extrusion, max ray distance and a cage preview
Bake Mesh Maps	writes the maps into <blend>_Data/Textures/Baked Maps next to the .blend

Generator Inputs can also create or bake the helper maps required by one generator. This panel is for baking standalone map files, or a complete set of maps, rather than configuring one generator's inputs.
