hi,
here is a new tutorial again about highpoly stones, but now we only use 3dsmax and no sculpting software.
you will learn how to setup a fancy modeling rig only with modifiers and procedural maps.
no plugins or stuff needed.
once you setup this stuff you can produce endless variations of stones, only by changing the mappingoffset in the first displacement map.
mapping and texturing (non destructive for the highpoly, which is interesting for cg renderings) will come later as also the standard workflow to make this a game-ready asset.
i hope you like it!
