Volume - Position Offset

 

This tutorial shows how it is possible to offset where a volume is sampled using a noise shader connected to the 'position offset' attribute of the Volume Collector shader. You can create some interesting effects using this technique, for example, animating the noise shader to represent some flowing gaseous smoke. We will be using a noise shader in this example, however you can use any texture map to offset the volume.

That concludes this tutorial on the 'position offset' attribute of the Volume Collector shader.

 

 

The images below show the effect of using different noise types connected to the Volume Collector's Position Offset attribute.
