i like to give away a solution to bring some displacement into octane/c4d.
The idea is based on aoktar´s solution for Volumetric Clouds here http://render.otoy.com/forum/viewtopic. ... 53#p161897
THX for the cloudsfile and the idea of the further usage of the c4d displacer.
The amount of detail can be controlled with the CNURBS division and/or using a HYPERNURBS.
The textures are taken from http://cgtextures.com/ http://cgtextures.com/texview.php?id=72 ... k3vqgrsdh1
Just play with it and have some fun
