The changes are nearing completion. Soon there will be an updated version.

better make a totaly new tut then , and sent encountered bugs to the dev that developed the new particle system. ;)

I have noticed that the new system, even with cache, is slower… This jet engine uses a lot of particles, and I used to be able to speed it up by setting the "disp" parameter low, to display only a few particles, but that has little effect in 2.46. That is, visually it has effect, but not in terms of speed.

Anyway, the particle system has been (partially) fixed, but the particle deflectors behave strange as well, and I can only see a bug as the reason. With damping 1, they still bounce particles, whereas new meshes with the exact same deflection settings, do behave properly.

And, the material needs tweaking, because that too looks different.

The new particle system really needs to be more friendly. I wonder if its documentation is even done yet.

Ah, I found out what's wrong. See the compatibilty note at:

http://www.blender.org/development/release-logs/blender-246/particles/

I will be correcting the particle system soon…

I do see something, but not particles… I white line jumping all over the place…

The thing is, the particles are being calculated. I notice because of the slowdown. But they are not shown; in the viewport nor the render. And even when I create a new mesh with a new emitter, no particles are shown.

Go to the bake tab in the particle buttons section and press the 'bake' button for the desired frames. Do the particles show up then?

Hi, I'm the author of the tutorial in question. For those of you who download the blend files, you may notice that the particle system doesn't work in 2.46 anymore. I don't know how to fix that. Even if I make a new particle emitter in that same project, it doesn't render. Any tips are welcome.
