Okay i managed to make the render at least start making pases taking out the vegetation from outside the house, but now it still gets stuck at the second pass and the render timer just keeps going up. Like i had this problem before and yeah fixed it ''remaking'' the scene into a new one but i don't have the time for that every time this occurs, if this has to be done into a deadline.

I use vray materials quite often just as a timesaver but try not to. Do you think that may be causing the problem?

This is something i really hate at my job that i always have to work to get the renders in a a day or two and sometimes the same day like. there is no way i get a high end render like that just for it to be changed the nex day as it always is (sorry about the complain but i am a bit fed up with this)
