VRayEnvironmentFog woes

[twinmold]

I'm trying to figure the whole Fog effect business (and pretty much starting with Blender +V-Ray), but so far every step on my progress has been painfully slow, so I though I might as well ask you guys and document the feature here for anyone interested. I'm using this reference guide. So my main points of inquiry would be:

1) How do you map textures to the color/density/emission values? (as seen in this examples)

2) I only get any kind of result using "gizmos" for the volume (say, a huge box containing the scene). I can't seem to make the "height" method work.

Any help or a bit of explanation on how the features translate through blender will be appreciated.

Re: VRayEnvironmentFog woes

Hi,
mapping textures to control fog behaviour isn't implemented yet (afaik). Fog height parameter was working well recently, but Blender still changes these days, so it may not be stable enough.
I also was only able to get predictable results if used gizmo in my scenes.
The main fog density/sampling parameters were responding correctly according to their description at "Chaos" site..

Fog mapping would be great functonality indeed.. I can think of multi-gizmo setups as partial workaround..
