How To Simulate A Fast Moving Object?

[jsahn]

hello,
i'm animating a fast moving arrow against a forest background.
can you tell me the most efficient way to simulate the speed?

the camera is following the arrow, but to make the background pass fast, i need to have more paint effects trees and the arrow needs to travel a greater distance, which is beyond what my computer can handle. what would be the best way to do this without compromising the quality.

thanks in advance,

h.

redner 2 layers one for arrow and one for background then use a post processing motion blur.

hi joojaa,
thanks for the tip. the motion blur certainly helps it look like it's moving fast, but the background itself is still moving slowly, so i ended up using alpha images instead of paint effects trees. it'll do the job for now.

thanks a lot!

well you didnt usnderstand my answer . Post processing = not in maya, use your comp app for the motion blur. pfx is not real geometrey so it does nt have properties of real geo either.

sorry for not explaining it to you clearly.
i actually converted the paintFx trees to polys, so i can render them in mental ray, so the geometries got dense.
i used after effects to do the motion blur, but couldn't achieve the result i need.
sorry for the confusion. i don't know if you have any other suggestions, but i went ahead and used alpha mapped tree images instead.

thanks for your help!
