Hi Michael.

Thanks for post.

So I did AK bullet tutorial, and also I saw a couple of tutorials on displacement mapping to get to know the basics. And basicly I found out it uses a image/clip to distort another ( target layer ). It moves the pixelse around either vertically or horizontally.

But I ran my head nuts, cause when I get to the actually part where I distort the bullet trail as in AK tutorial, instead of displacing pixels around the trail, it moves my background vertically or horizontally?? I made a trail right behind the bullet and I want to displace that part only.

Can I make a copy of the bullet it self and make that displace to the background? And then set the displaced bullet a couple of frames behind the visible bullet??

I really want this to work, I spent many hours on this and also I find my self to have learned so much in the progress, really love AE, but I am really stuck here…

I cant make a copy of the bullet and use that as a displacement map since I also imported the camera data from cinema4d.

Is it possible to just draw some sort of a trail and keyframe it to follow the bullet and then make a displacement of it so it blends with the background?

I have a lot of layers and precomps in my comp and my background precomp is located in the bottom of all layers, where do I put my drawing layer compared to the background in order to make the displacement blend with only the background?
