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

i think motion blur is the phrase you're looking for. one way to do it would be to use render to texture and draw the last few frames along with the current frame to the screen each loop.

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 don't see why, you aren't rendering to 5 different textures each frame, just cycling the active one through the available ones and drawing X*2 triangles on top of each other with varying transparrencies (or calling draw2dimage X times). older graphics cards won't like the rtt though.

Or you could use shaders

Have you seen that awesome motion blur example that comes with rendermonkey? Try it out!
