Hi Neuroup,

You could try ground fog. The control panel lets you set the lower and higher level that the fog should start and finish at.

Hope this helps.

I'd reccomend using hd_groundfog: http://www.happy-digital.com/freebies/groundfog.html
It renders incredibly faster than does LWs normal groundfog, but you have less control over it. What it looks like you're trying to do, can be easily done with this plugin.

Thank you for help.
There is one problem. I did'nt use ground fog ever. Can you write me something more about it? Maybe some presents? I don't know how to start even.

Bye!

with HD_Groundfog:
falloff- higher values make it level off faster. It gives a really thick, heavy fog effect (prolly not what you're looking for). Lower values make it "spread" more and cover more area and slowly fade off

exponent: how thick the fog is. The higher the values, the thicker the fog, but it also seems to basically do the same thing falloff does

groundlevel: tells you where the fog is 100% thick. Basically, the point where if the camera goes into, you can't see a thing. Unfortunately, you can't define a bottom as you can do with lws default groundfog.

Just play around with the options for a while (BTW if you don't know how to get there, just go to Scene->Volumetrics->Add Volumetrics

This is very nice that you write this information about my problem. But i didn't ever use this plugin. i was trying to do it[step by step from your post] but there wasn't any results. Can you write some more information and maybe more precisely ?

Thx for your help.

first, unzip the plugin, then go to Layout->plugins->Add Plugins Then find HD_Groundfog and add it. Then go to Scene->Volumetrics->Add Volumetrics-HD_Groundfog, and make certain there's a check next to it. You should now have fog in your scene (the defaults are really strong btw, so you'll have to tweek it a bit so that it dosen't blot out your whole scene). Hope this helps.
