brush flow irregular

My brush suddenly stops when i draw a single stroke.
Most of my brush strokes are irregular in adding mass, meaning when I wish to draw a stroke of clay from a to d, the brush suddenly stops at B.

specs
surface derived from zsphere and zsketch unified skin.
Contains alot of N-poles and E poles due polygroups.

which version of Zbrush are you using? Zbrush can only maintain a single stroke for so long…basically think of it as a caulk gun…you only have so much caulk you can get out per squeeze of the handle. The same thing applies to the way brushes work in Zbrush.

Mostly it’s a RAM issue that causes this to happen, but you can get a much longer stroke in 3.5r3 than you could in 2 or 3.

Been using zbrus since 3.0 to 3.5 R3, 4 years by now.
Never encountered a problem with irregular brush strokes.
Dots are off.
Freehand turned on.
8 Gb of ram

The geometry is derived from a zsphere with zsketch turned on, it contains alot of poles, due zsketch, poles create spikes in zbrush, easy to fix
I don’t understand why zbrush doesnt allow me to create a stroke, its broken.

I must not have interpreted your question correctly.
I still don’t quite understand what the problem is you’re having? Can you post up some images of the problem?
