Hello. I am completely new to ZBrush. I watched a tutorial and am trying to do my first project. I am wanting to use an image as an alpha and turn it into 3D. It works, but the edges are very rough and there are some random floaty bits. Is it because my image is raster and not vector? The tutorial just used a png and it came out great. Maybe somebody can give me some pointers? I am including my png and a screencap of my result. Thanks so much for any help.
