Thanks for your responses....yes i've changed the angle of my camera and reduced the amount of grass but still quits :S... my dynamic memory limit is 5000 .. it seems ill have to use photoshop instead

hey guys i have a problem.... i'm trying to render a 25MB model with vray.. i have skp8 pro and vray version 1.49.01 i have a macbook pro with 8GB ram so here is the problem my scene has grass so im trying to use displacement but when i try to render the buffer comes up and after 2 min sketchup quits unexpectedly but the weird part is that i've render the same scene before with displacement and it seemed to render fine but now it just quits. i dont know what is wrong because when i turn off the displacement it doesn't quit. pliz help me
