I very recently transitioned from ArtRage 3 to ArtRage 4.

In ArtRage 3, I was able to whisk the water color tool such that it ended in a very fine point. I used this technique quite frequently (ex. mountain tops, grass blades). In ArtRage 4, the water color tool tapers off in a blunt, round manner. As far as I can tell, the tool seems less interactive with touch pressure now. Is there a setting to change this?

I can upload example illustrations if that will help clarify the effect I am trying to accomplish.

Thank you.
