twelve managing the Fog effect

You can contain this fog effect within geometry by using a Readgeo node to bring in an obj and plugging it into the obj input of your Vrayenvironmentfog node. Your fog effect will now be contained within this read in geometry. It takes a fair bit of nudging sliders in order to get the exact look you want, but it’s something I’ve found I’m using more and more now I have access to it.
