View Full Version : Rock Modelling

Hi,

I've tried to go as procedural as possible while modelling an arc shaped rock structure using metaball, a base primitive, some displacement nodes and a rig to shape and bend the structure to my liking (credits to Mr Douglas for coming up with the bone idea and file). A problem which I'm facing now is that the edges of the model are not as sharp as it should be since it's using metaball which serves a more organic purpose. According to one of my lecturers it's pretty bubbly and round and real rocks are supposed to be sharp and rough.

I've also modelled a couple of rocks in Maya and found it's much easier to direct the look I want with all the sharp edges needed. However it's not as procedural as when it's done in Houdini using the metaball method.

So does anyone know a way to "sharpen" metaball generated models in Houdini? Any help would be much appreciated! (:

Here's the link to the hipc file I'm working on.

Tricky situation. To sharpen your rocks check out this thread with some cool example files.
