I am looking for some good game engines that allow deformable terrain (Voxel engines are fine too as long as they allow terrain deformation, and allow graphics better that minecraft)

I have good knowledge in C++ and C# as well as SQL databases, and some knowledge in lua. I'm just trying to find an engine that already allows this over a network, as im not too good with scripting network interface.

So far I have tried C4, which didn't seem to work too well for my goals, Visual 3d which doesn't have up-to-date networking last time I checked (on the features page they say they do, but many forum posts by their own staff seem to say otherwise) and in udk I have tried the fractal mesh system but that didn't work too well for whole terrains. Any ideas?

Thanks!!!!

as far as i know cry engin is the on open engin that has deformable terrain i use cry3 and it works pretty good for my design theres a good indepth video called eat3d that showed me some things I didnt think of or know the engin was able to do

This was a plugin for Unity http://www.voxelform.com/

Here's a concept video for a refreshing game being built by 2 guys with Unity:

It has deformable terrain as well as procedural base creation.
