thank you profbetis i can do fog, but exist a problem, dark sides and a strange image, any idea ?

Merid, try to make your fog volume fill up as much of the room as possible, otherwise it's like having a big block of fog in the middle of your room which isn't realistic. This is also what's causing the weird lighting issues you're asking about.

Also make sure your depths are high enough (on direct lighting: specular depth; on pathtracing/pmc: maxdepth), they should be around 8-12

man make a sphere

Oh I would be so happy to get motion blur. Real Smart motion blur (fusion plugin) is fantastic thing but it does not making sence when you use very very high speed moving objects as I do. Pleeeeease

regards

sorry its not opened. obj pleace.
I think in your scene objects are touching eachother, and turns on the black "hole"

also you have to make sure the sphere around the camera has inverted normals (usually they point outwards, make them point inwards) and have the same fog material as the volume that it's inside

Fog doesn't work with Direct Light kernel well.
