Apologies for mailing you directly Simon . My webmail client does that with some replies.
I am actually considering a different method for solving this shot - what I need to do is create a small traveling patch of grass on a hard flat surface, which should appears as if it quickly grows up and then shrinks away again when the area of interest moves. My plan was to create a nice grass plane which follows a generator surface which I then would push up through the hard surface with a traveling matte texture driving a push deformer or an ICE translate node. Another way would be to map the size and length of the grass strands directly with the values from the traveling matte, but when I try and grab those in the pointcloud ICE tree I get a context mismatch between pointcloud and polymesh. How do I transfer a scalar value from a polymesh to a pointcloud?
