Thanks for answering Alain.

I'll add that the component shape functions for the wall and paint are 
thin - using scaled abs(z)-image. While the peel height can be increased 
or decreased, it is just a displacement in z and so the struggle is 
keeping a realistic peeling look as the displacement amount changes.

Related, it is possible to play with the gamma used while reading the 
image to change the blur profile to perhaps get more of a curl to the 
peel, but I've not yet played with that technique on this peeling paint 
isosurface.

I've posted a zip of code posted to p.b.scene-files.
