In my current version, 5.0.0-beta1 (git 9bd5348), I cannot add any texture settings to a newly created smudge engine brush. The brush acts as if it doesn't consider the 'pattern' and 'strength' settings at all, regardless of any combination of other settings I use. I have yet to get even a semblance of a change in the brush, so I assume it is broken or deprecated on my version.
I can partially reproduce the issue. The pattern randomly disappears from the local resources snapshot in about 1 stroke out of 20.
