Hi,

You can do it either way.  Having multiple TMDs costs memory.  Modifying
TMDs costs processor time.  When modifying TMD prims (not verts or norms)
you should re-link the object before sorting into the OT.  You can save
memory by sharing verts and norms across multiple TMDs if it's just the
prims which are different.

Oh, and TMD sprites (and lines and double sided polys) are not supported in
the NY libs.
