Dusty atmosphere
show user profile  Lazmo67
Any one got any ideas on how to achieve a dusty atmosphere. Re working an aircraft hangar on a scene and i'd like a "light beams through dust" type effect.

Volume lights??

My PC is struggling with the scene as is so anything not too processor hungry would be good, if, probably not, probable!

I read a good article/tutorial a while ago explaining how you can render out volumetric fog/ambient occlusion etc in a pass, then just comp the layers together in p-shop etc. Was utterly useless to me as I don't really do that kind of 3D work, and as such, I didn't bookmark the page or remember the author/site etc.

Yeh volumetric but what LionDebt says is true you can use a simple z-depth pass as a comp layer to create depth fog which can be tweaked to suit.. you can also use it to other interesting effect such as desaturating or colour tinting the scene as it recedes into the background etc..

Brilliant, just what I was looking for. I'll give that a try when the wife has calmed down (Max widow syndrome) and I can get back on the computer! lol

You can achieve this easily in Maya. You will find many tutorials in the Internet.

That volume light pass is definately the way to go. been experimenting with it and it produces exactly what i'm after but I think I'm doing something wrong because it's taking an ice age to render!!

slight effect on the lights but going to dump that and use it through the skylights. no time to do a high res as yet.
