In a previous version of Blender 2.80 I’m doing a masking method and also using the build modifier and it works perfect . So I downloaded 2…92 and did the same exactly method, but its extremely laggy, and blender wont respond and then at some point crashes. what could be causing this issue? its working fine with previous version but new version is not working well. Here’s a file if someone wants to test it as see if the new blender 2.92 works.
