Labs Map Baker - Bake Per Piece Using Name 2022年2月15日10:42

Your high and lowpoly need to share a name attribute. It will then function as a mask so to speak.

Imagine if you have a metal panel with screws in it. (In both your high and low).

To get a clean bake, you would want the lowpoly screws to only sample from the matching highpoly screws, and not the (intersecting) panel. To get proper results you would therefore add matching name attributes on both the high and low and turn on that toggle.

Problem with diffuse map baking. Example included. 2022年2月5日13:10

As of last Friday, MapsBaker has support for material_overrides, fixing the bug you mention above!
