Hi everyone,
I’m pretty new to ZBrush and I was attempting to make a custom brush after watching a tutorial.
So I tried to make a stroke brush by cloning Standard brush and replacing its alpha with a custom alpha.
It has Lazy mouse feature turned on and stroke is set at Freehand.
As seen from the screenshot below, the ‘spacing’ (not sure what’s the term for this) looks weird which makes this stroke looks dotted. I looked around for a solution to adjust the ‘spacing’ but couldn’t find it 
If anyone has a suggestion or a way out, please let me know. I’d really appreciate it. Thank you so much.
