The “Baking” dialog box opens.

Uncheck unnecessary maps in “Mesh Maps” on the left of the “Baking” dialog box

Then you change “Match” parameters from ”All Ways” to ”By Mesh Mame”. The high and low mesh’s suffix parameters are highlighted. Please enter the same characters each suffix of the objects. Please be careful, it is not about file names. It is the suffix of the name of the object in the file. Also uppercase and lowercase letters are recognized.
