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!

Brian forgets to say that 3D Coat is one of the first to propose in new Alpha version the technic of "Voxels" (Volumetric pixel, "grain of clay" ;)

ps You must have new strong graphic Video card !

This remarkable little offering from Argile is certainly worth checking out for value should you need to sculpture, paint or add photographic texture your exported mesh: http://www.n-sided.com/3D/argile.php?rub=1

The three short videos on the home page demonstrate the modest aspirations of this neat package.
