Timex

Maybe someone could help me with this... I have a mesh and in the voxtree is represented as Voxel so it has the V icon, I exported 2 models, one in V and other in S, both using right click and Export Object. I suppose both models should be the same but as soon I import it on Mudbox, It keeps telling me that the model exported in V mode has errors. Thats a bit awkward and I don't know exactly what is happening here, maybe I'm wrong but I think export in V mode should change internally into S mode before Exporting. This is nothing that keeps me away I just need to be sure I'm in S mode before exporting and thats is easy to forget. Maybe someone could give me more info about this, thanks.
