Hi,

If you use the fur SOP for rendering you can simply use a Point SOP (or a
VOP SOP) after it to deform your geometry.

As the Fur SOP remove the Origin attribute you can use the Attribute
transfert SOP to get it after the fur SOP.

Here is an example using a Point SOP :
Create a "scale" parameter and replace $TY by ch("scale")* rand($PR) * ($TY
- $ORIGINY). It is similar to the random scale formula from the CVEX shader.

But if you use the Procedural Fur shader for rendering you should use the
CVEX shader in order to randomly scale each strands. CVEX is not difficulte
and it is easy to load the random scale one from the help :-).

Cheers
