Photoshop Auto Rotate Brushes

Hi there!

Right direction - I just meant, can someone with the knowledge on this topic lead me to the answer.

I'm not sure I can capture this in screenshots. I'll try to explain better. I have several brushes I downloaded for skin texture. Specifically, freckles. When I paint with the freckle brush, each time I end a stroke, the rotation of the brush automatically changes so that when I paint with it again, the freckles are turned and not looking repeated. I don't do anything with my arrow keys to change the rotation, it's set up in some way to automatically do this. It's fantastic for making skin texture or fur more random and natural without having to manually rotate the brush after each stroke. Since the brushes came this way, I haven't been able to figure out how to replicate that feature on other brushes I'd like to set up in the same way.

Does this make more sense? Thank you for your reply.
