I edit the basis and it changes some of the shape keys. Every shape key in the file has a driver, but only few are affected by changing the basis, and i can’t figure out why precisely those shape keys and not the others.
Sorry for no file, but it’s kinda secret project, plus somehow i can not recreate the bug (or whatever rule that is) on an alternative model, because i simply don’t know what am i doing wrong. Besides i do can exclude vertices from a shape key by “blend from shape” option, so broken shape keys aren’t my problem. The problem is what can cause this affectedness, so i won’t do this mistake in the future. Any ideas please? It’s 2.78.4 version.
