Odd squares preventing sculpting

[Ugahbugah]

While trying to detail certain subtools, these squares pop up over the area I’m drawing. They appear as I sculpt over the area. This error is preventing smooth rolling of the alpha, and destroying my detail.

Any idea what causes this? It’s only happening on one subtool, not the others. I’ve tried reloading the subtool, restarting ZBrush, restarting my computer, etc. Nothing is working.

What brush stroke are you using? Without knowing specifically the effect you want from the alpha, you can try the Drag Rect stroke to draw out single instances of the alpha. Other strokes such as Spray, Dots etc. will give multiple instances on the mesh.
