Hey guys, I'm very new to 3D Coat but I'm also trying it out. Using the free trial before I get onto my final decision of buying it. xD
But, I'm also trying to attempt to practice on a simple sphere nor one of my exported characters I sculpt on Sculptris and tried to retopo it on Maya. So far I'm lousy at that, but when I have seen 3D Coat's amazing tools that's built from ground up for Retopology and now it's available for the Mac. It makes 3D modeling far easier than I thought.
But, at my first attempt to try retopoing one of the samples. The mesh ends up disappearing when I select a basic tools like Points/Faces to start retopo. But they also start out so very small so I enlarge them to see them with out having to zoom in and end up having difficulty rotating the camera.
