Maybe I shoulda wrote: using ‘texture engine’, instead of ‘texture’ I guess. I used plain texture to show the behaviour.
I think this is probably related to this post. And I think now I understand it may be impossible to separate texture behaviour like I originally suggested.
I’m not sure you will make it so that both ‘per stroke’ ‘per tip’ are avaliable in the texture engine in the future, but it would be the ultimate solution to all these including emulating other brushes used in other programs.
