Help with IMM brushes


Hello, I am trying to make some sequoia leaves in Zbrush, so I made an IMM brush to help with the process, however, every time I use it, I get weird artifacts and it connects to the wrong spot. I’m wondering if anyone knows what’s happening here. Thanks in advance!

Attached is an image of the problem area, showing where the artifacting is happening and where it is attaching to the leaf rather than the stem.
