[Bf-python] Extracting cloth vertices position

[Bastien Montagne]

Hi,

Yep, this way you’ll only get org data, before any modifier is applied… 
Since cloth's pointcache data do not seem to be available from Python, 
the only thing you can do to get cloth cos of vertices is to applies all 
modifiers, like this e.g.:

     # Generate temp mesh from object, with modifiers applied.
     tmp_me = obj.to_mesh(/scene/, True, '/RENDER///')

     # Use data from tmp_me...

     # And then free it!
bpy.data.meshes.remove(tmp_me)
