Hoping that someone can help with this, I have an issue with zbrush 4r8 on my Surface Book. When I put the pen to the screen it doesn’t register that I have done so, I can even move the pen around a little bit without it doing anything to the mesh on screen, as soon as I move far enough it starts to work. It doesn’t matter how hard I press down on the screen, it doesn’t do anything until I move the pen along the surface. This happens on both zbrush Core and 4r8 but doesn’t happen in photoshop. I have updated and re-installed the WinTabx64 drivers and the pressure sensitivity works fine. If anyone uses a surface device and has fixed the problem, please let me know!
