PropViewer can handle and process big meshes as 10 million polygons. I don't tried bigger.

In general survives to corrupt meshes without crashing and tries to repair it whenever is possible.

You can load Poser meshes with internal geometry (pp2, cr2, hr2) and dynamic hair and can load 3ds, obj, dxf, ply, off and stl formats.

Can export as obj, pp2 and LuxRender (lxo+lxm+lxs)

You can perform several operations with the mesh: Reverse normals, Mirror,X,Y,Z; Weld, Convert to quads, Convert to triangles, Split, Smooth (taubin), Subdivision (Middle-point), Fix normals, Remove duplicated faces, Remove non two-manifold faces

Just finished something like drape or convert to a regular mesh (don't know can call it)

Not all these features are present in the uploaded version.

 

Working in other subdivision schemes, decimation and Poisson reconstruct (turn point cloud into a mesh)

Stupidity also evolves!
