Global Fog

[bhamill]

i want to use global fog in my scene, but i can't find any shader solution for that problem. in the mental ray handbook vol1 is a example for global fog, but i don't know, how can i make it so. i'd tryed various things without result.

Go to Render>Edit>Current Pass>Volume Shaders and chose Volume_fog or whatever you want.

the problem is, it doesn't function. only the "background" of the rendered image change the color.
now, i use 2 volume lights for the effect, not the same, but it works.

Sure it works. You need to set the start and end distance. Easily done in one minute.

You can "manually" do the function by switching to Passes in the Explorer, click on the pass icon, go in the Volume Shaders tab, click Add, choose Constent_Density or Volume_fog, then click Inspect to edit the parameters.

Hope this helps

thanks for replys.
i tryed all out, but it dosn't work, i don't know why, but it does't function. i use now a volume light and in the global volume properties i'd activated the depht fading option. it looks good, but the volume must ever be visible for the camera there with it funtion. and for final adjustment i will use photoshop.
