Thanks Steve.
I am aware of most of what you stated in your reply
I am using a Physical sky in the scene and bump maps dont quite get there
Displacement with subdivision gets there …. its not an animation (yet) so render times are not a big issue
I have never used the deformation effector in Mograph I am still in the dark past with R14
I suppose what I was hinting at is if there is a procedural approach rather than using images
Any thought on this?
Regards
Greg
