I just tried the demo. This does create high poly meshes for sure, It has a built in reducer, which works ok. But I personally would build a base mesh in another modeling program, then use
http://3d-coat.com/ to paint and do your normal maps. 3d coat is amazing! Been using it since it was first released. You can create awesome normal maps in realtime without adding polys. It does have a sculpting feature which I never touched yet, to build models from scratch. But I am an old school poly modeler so build my meshes from box or face extrusions, then paint my normals. Sculpting has come a long way though so you might find a different way than mine
I would definitely try out the 3dcoat demo and see if you like it. And The educational license they offer is not just for those involved in education anymore and is only 99 dollars, same as curvy.
Direct quote from website:
The policy on the 3D-Coat Educational version have been changed. We offer 3D-Coat to students, hobbyists and amateurs pursuing non-commercial goals, so as senior people and unemployed at $99 US.
FROGS!
