The great (low price)3D displacement/painting app, 3D Coat, has been around for quite a few months now.
It is really --by any standards--great value for money.

But those of us with it are able to try out the Version 3 Alpha/Beta.
Ohhh!--what fun!
Here is an example of my very first few seconds just "fiddling"!

MoI,Carrara6Pro, and 3D Coat---WOW!
