Bullettrail - "Matrix-Move" possible? [ANSWER]

I think the Bullettrail Effect is a great feature, but I have a question - is it possible to build it into a rotation, just like in Matrix (rooftop scene)?
For this I'd have to define a start and an ending point; this is not possible, am I right that I can't build it into a rotation?

You can ask Sollthar... his clip is here

It would be very difficult to do a bullet trail in EffectsLab with a rotating camera. The particle generator in EffectsLab doesn't have the 3d capabilities you would need to do that properly. I suspect that you would need a proper 3d application to accomplish that.

If you could somehow work the bullet trail textures into the muzzleflash engine, you could simulate the 3d rotation. The muzzle engine is really not at all designed for that at all though, but it might be feasible to achieve something similar to that effect.

thanks for the information!
I think in this case it's impossible to use Bullettrail if there's not a static shot?
A minimal change of the point of view may cause it looks terrible; am I right?
(sorry for all the stupid question, I'm totally new to FXhome)
Have a nice evening!

Yeah, that's correct. It'll work for locked shots, possibly even minor pans or parallel trucks, but an orbiting camera move isn't curently feasible.
As far as the muzzle flash idea, the Flare engine randomly assigns a bunch of copies of the textures to particles to create the muzzle flash, and even then, they aren't true 3D particles, the just have a picture (texture) pasted on one side. The 3D abilities of the muzzle flashes work based on the particles' positions relative to each other, rather than a 3D shape of each particle, so I don't think that would work in this case, either. But I like the way you are thinking, SGB. Pushing various elements of the program, and getting them to work for things they weren't intended for is always fun, and can occasionally bring stellar results.

What if one had an animation made in a 3D app of a cylindrical shape with an amimated texture, following the camera move as the bullet trail, then composited it into the shot and applied a displacement map to it? I imagine that would look decent.

Yeah, that could work. But then, you might be better off just compositing it right in the 3d app. Depends which 3d program you are using, I guess. But if you animated the wave ripple and tracked the camera to match the move, you could easily composite that into the scene and displace it using EffectsLab.
