Hi all,
My question is very simple : is it possible to have more than one particle system on one single mesh, and if yes, how ?
No - I don’t think so anyway.
But it depends on the desired particle effect, you may be able to do what I did in a recent project.
I created several separate meshes with a pre-determined number of verts/faces within the same object. Then using curve guides and the min-dist value, I moved the start of the guide with min-dist sphere encompassing the particular mesh I wanted to guide.
I’ll post a screenie in a minute.
One object with three meshes inside it. Curve ~centered~ on each one.
do you have s small tut on this
this effect could be used to simulate the wind pattern of fans

Well I don’t have time to make a full pictured tute, but here it goes:
Assumption: You are already somewhat familiar with the particle system in Blender 2.4x and curve guides. If not, browse the wiki.
setup:
Decide how many guides will be coming from the object, and the percentage of the particles to go along each guide.
- Select your emitter object.
- Turn on particles.
- Set your particle count, life span, start/end frame…etc.
- Turn on vect.
- Enable B-Spline
- Tab into your object (edit mode).
- Reform your desired meshes - I like to use a total of 100 verts, emitting from verts only, and you can control your percentage of particles coming from each mesh by the number of verts. (In the pic above, obviously there are 33% of the total particle count flowing down each curve guide).
- Tab into Object mode.
- Add Bezier Curve. Move your curve points around in the desired spots, making sure the originating point (usually the left when you first create it) is centered approximately over the desired set of verts from which the particles for that guide will be flowing… :o .
- Tab out of edit mode, and In the physics tab, enable Curve Guide as a field type. Adjust the min distance so that the sphere encompasses the desired set of verts.
- Repeat 9 & 10 for any further guides.
- Turn on and play with max dist and fall off if you want the ends of the guides to have a lesser influence and allow the particles to flow randomly.
- Alt-A to watch it (Alternatively you could set the particle emitter system to static to see your results in real time).
I hope that’s clear enough.
i will try it this weekend
when you say bezier curve
are you talking about the black line that we see and or the circles on the right ?

View that for a pictorialized version of what I said above. Bezier curve is the entire curve. The circle is the sphere of influence defined by the Min Dist Value.

for the blend.
Ok, thank you. So the following question is : is it possible to use the material of the emmitting part of the mesh for the particles (and if yes, how) ?
I think you can only have one material for the emitter - regardless of how many curves you use.
Ok, that’s a pity, but thank you very much.
