Vray Env Fog 10Km/10000m limit?

[Steve_Green]

Hi,

Just getting back into vray after a while - is there any way of getting around the arbitrary distance limit in Vray, or to just change the overall density of the fog if I want a light mist.

Is the proper way to put something like a noise map with the same colour to lower the density? It bumps up the render time when I try that, so I wondered if I'm doing it totally wrong.

Thanks,

Steve

You can set whatever values you like from MaxScript.

Nope.

If you put a texture, V-Ray switches to raymarching rather than uniform sampling of the fog; this tends to be slower.

Hi,

Thanks - thought it might have been hard-coded.

I don't really get why limits are set for a lot of these things in the UI generally - I can understand it for things which might kill the scene, like iterations on geometry.

Cheers

The 3ds Max API requires limits to be specified for each parameter.

Ah right, OK thanks.
