How can I create lines with uniform Zintensity and size?? This you could achieve by simply pressing the Shift-key in older versions. Now you have to go in and disable lazy mouse and mess around with brush modifier settings and tabletPressure curves. What you could do by simply pressing a key is now a bloody nightmare in Zbrush 2018.
Lazy Nezumi is a very flexible way to do it.
Click and hold LMB (Left Mouse Button) but don’t move it. With LMB still held down, hold down Shift and draw out your line then, with LMB still down, let go of Shift. If you want to keep going but on a different angle, without letting go of LMB, press Shift again and draw out your line.
