Is this a new bug of Newest Version 11.1.1?
In the latest version 11.1.1, when using "Use Low Poly Mesh as High Poly Mesh" for texture baking

The Self Occlusion selection failed in Ambient Occlusion/Curvature/Thickness

The behavior of "Only Same Mesh Name" is identical to that of "Always". The attached image shows the AO baking maps in different Version.
