ok i have steam shooting out of a pipe right....and i guess half life 2 is built on the theory "if you cant see it it shouldnt be rendered". so it goes like this. i look at the steam....hmm looks ok. i took away. dont see steam cause im not looking at it. look back at it, and for about a split second steam looks like its only beginning to come out and then it just flows normally. how do i make it so that the steam is always coming out of the pipe and doesnt disappear when im not looking at it?
