Irrlicht Engine

Actualy trails and motion blur are different in some aspects but the way you suggested may just work although if you had a resolution from about 800x600 and higher wouldn't that slow the game down dramaticly?

I have not been able to find a Trails function in Irrlicht, is it possible and if so how? If you don't what Trails are I DON'T mean particle trails I mean like the trails that GTA3 used. Thanx
