I also have been hoping that 3DCoat could do in 1 tool what I now rely on two tool to get ready to send to Blender for DAE creation. It uses the same Voxel modeling that Sculptris uses and has a lot of additional modeling tools that Sculptris doesnt have.

So I decided to take a serious stab at 3DCoat. But I have learned that the ZBrush UV Master has become a critical part of getting the Scultpris model ready for exporting to Blender which in turn can create the DAE file. I love Sculptris and thanks to some advice from this thread I have even been able to learn how to use Sculptris's polycount reduction tool and reduction brush tool to make some really cool artistic models to bring into SL. I have been experimenting wirh many tools and different workflows. So lets say I have point x, and I want to snap it to its closest green dot(here the green dot isn't a point on a sphere but actually a point on a 'cartesian' grid), so to snap point x I just do round(x / gridSize) * gridSize and that snaps x to its closest grid point, but in my case I need it on a sphere, so how can I convert that to snap to a spehre? IDK if I'm making any sesne.Throughout January I have been trying to figure out the best workflow to get a 3D Model frmo being sculpted to being textured to getting into SL with what was sculpted and textured. An example of how this could work if I didn't need it to be on a sphere is this, So how can I make any point in space snap to the closest green dot? And IK I could just loop through those points to check the closest one, but there are gonna be MANY of these points so its not a solution and so any point has to find its closest green dot without distance checks. In the picture I have green dots which represent the possible places(there are more of them) that any point in space could snap to.

So I need to snap any floating point in 3D space to the nearest point on a sphere, the size of the sphere also needs to change as the point gets further from the origin, idk if that made sense or I'm just thinking about something incorrectly, but I made a picture of it in blender:
