Basically i´m a newbie in what comes about rendering, but i also like to make renderings in the render farm. A few weeks ago i discovered the volumetric lighting option wich Scrubs added to the render mode, and i was wondering how i can use it, because in some tests i´ve made i just can see everything in a grey color. Perhaps i´m using the wrong parameters.
Could someone give me a example of how to use this function?
Thanks in advance

You need to adjust the density parameter to get it right. This value depends on the size of the box and is generally very small.
Having a value of 0.0001 wouldn't be weird if your box is big.

I also recommend to wrap your whole scene inside the box as well as the camera.

When I use volumetric lighting in my renders I end up with a weird pixellated effect around the lamp which is an area lamp. Can someone please tell me how to fix this.

I think the problem might be because the lamp is at the same level as the floor, and nothing to do with volumetric lighting, but I can't test this because I hit the free render limit for the day. Gosh, I've been doing a lot of rendering.
