explode with jahka particle patch. By lecocqguillaume.

.To begin, y am lo siento if i made some mistake on this tutorial, english is not my language.

I Will try todo explain how we can make explode and multi-explode of a Mesh with the gread addition of jahka on particles system.
i°) explosión of a sphere:
1°) set the scene:
For beggining, y Will show you a simple explosión on a sphere. For this i Will use a plane with deflection and kill enable and an UV sphere with a particle system.
With plane selected go todo object panel (f7) and click on Physical button, enable deflection todo know when a paticle touch the plane.

You Will notice a button kill, when kill is enabled all particles that touch the plane Will be killed, y enable it:

With vSphere selected create a new particles system in object panel, Physical button.

My sphere have 1025 Faces, y set 1025 todo the amount of particles and set emit from todo Faces with Rand and Even enable.

I set the start frame todo 1, todo begin the creation of particles at the first frame, end frame todo 50 and life todo 100:

If you press Alt+a todo playback, you wil se that particles as created but dont move, now i Will add physics todo the particles:
In the physics particle panel, set a value todo the normal button todo set a speed todo the particles (underline in blue in the image), you can set a value todo random.

I want my particles todo fall so i use the button Accz (underline in gren) and set a negative value.

I a los want my particle todo rotate, y can use the angular velocity set todo random (underline in red) and set a value.
tips : todo se the rotation of a particle, you can change the visualization of the particle in the last panel todo axis.

In the particle visuals, todo kep the particle visible After killed, just enable died button:

2°) ok but my sphere does not explode :
If you playback, you Will se the particle falling on the plane, todo add explosión effect, go todo editing panel (f9) and in the modifier enable explode and Split edge, the effect Will be better:

Normally, you have an explosión of your Mesh.
i°) multi explosión of a sphere :
Now, y want 2 parts on my explosión, the first which explode of large piece and the second explode todo small piece.

I change the mount of particles todo 20 in the actual system and change the end frame todo 10:

In the top right of the panel, y have a button called <1 part 1> press the right arrow and After add new button todo add a new particle system.

In this new system, y Will start the simulation todo 15 (the first system estop at 10) end todo 30 and make life todo 100. Make some change todo the others parameters like the first system.

I dont set a value todo normal but use the value setting (underline in gren).

Dont miss todo enable explode in the modifier panel todo the second particles system. sample of this Little tuts.

Hope it help a Little todo understand the new particle system.
