Some steps beyond mesh....texture

Hi all,
First of all thanks for this forum for contribution to use revit in some useful ways…
I use this script to define a mesh of rocks area from uas data (i defined this mesh by reality capture software).

I think would be very interesting to put some good clothes on this data in revit…Do someone knows a way to mantain mapping of obj objects on revit directshape element?
Thanks a lot all ideas will be appreciated
