Tried the 3D Converter but the files that I need to convert to are only possible in the registered version.

So attempting to get a model of an arm from Metasequoia to Sculptris was a bit of a task but I pulled it off.

First, I save in Metasequoia as a TrueSpace .cob file.
Next, In TrueSpace I saved as a .3ds file.
Finally, in Wings 3D I converted the .3ds file to an Wavefront .obj.

And it ported into Sculptris without much damage.

Anyone got a quicker way? LOL.
