It is NOT like we do not believe you hehe...

On the contrary,
These forums are viewed by everyone, so stating the basics first is a standard operating procedure, and neither Mike nor I meant to imply or accuse you of anything.

Anyhoo.....

I took a look at your playblast, and I noticed something that you did not mention in your first post about your problem.

It looks to me, like you are using some sort of volume in there?
Whether it be a volume field, and/or volume emitter?

This WILL make a difference if I am to try to re-create your problem later, so I will download your file to see what that is

Thanks!
