That's the sad part, Miss B. There is no current Sculptris. The last version was Alpha 6 from 2011. I think MeshMolder looks very competent, and I aim to put that through its paces over the weekend. As for remeshing, the Instant Meshes program I linked above might help with that. I think, if your class is using 2.8x and your computer can support it, it might be time to take the plunge for 2.8x. There are some good retopo plugins such as retopoflow and retopo MT.
