Hi matur61,

> Can you suggest me how can I convert this file in order to import in moi3d ?

Sculptris works on polygon mesh data, it's a different type of model data than the NURBS surface type of data that MoI is designed to work on.

MoI can convert it's own large spline surface sheets into polygons for export by dicing them up into little pieces, but it's not so easy to go the reverse way and take already diced up little facets and convert those into larger sheets. There is some specialized reverse engineering software that can do that, but it involves quite a bit of work and the software is expensive, it tends to be more meant for helping to convert 3D scans into CAD data.

So usually if you are working with polygon mesh type data, you will not be able to bring that data into MoI. You can export polygon data out from MoI but not import it back in to MoI.

There are some exceptions to this in certain special cases like if you're working with subdivision surfaces for the polygon data and use the T-splines program to convert it, but that probably won't be an option for using with Sculptris.

So you'd mainly focus on doing your entire job in Sculptris and not bringing that object into MoI at all...
