The "Voxel-Deform" is a small tool that allows you to paint-deform collapsed EPolys with primitives or custom Objects.
It is strongly inspired by the CryEngine2 Voxel-Tool for terrain deformation.
Unfortunately i can't offer the scripts but i can release a non commercial demo-version.
Feel free to use it and leave c&c
the latest version can be downloaded here:
max 9SP1 - max 2009
save the file fitting your max version somewhere on your hardDrive
in max goto MAXScript/Run Script and load the file.
