Modelling a cave

Hello all,

I am trying to model a cave like object or a carved out space with different articulated faces so it gives the appearance of a natural cave.



I am familiar with 3D AutoCAD, Rhino, Sketchup, Revit and 3DS Max.

Any help would be most appreciated. Thanks.


Here's an example of what I am trying to achieve.

I wonder if noise modifier would give you good enough look. If not, then probabely good displace map would be good idea for this. I mean to do it in max of course
