\"\"<\/p>\n

Lets create particles that converge to shape a rabbit from the shape of a ball and shape of an apple. Use Goal\u00a0Field\u00a0to create this movement.<\/p>\n

 <\/p>\n

We will be using orange particles that are mass particles and yellow particles that are particle emitters.
\nCreate an “Effect Root” and add “Particle Emitter” “Mass Particle Emitter”.
\nAdd to “Particle Emitter” a “Field<\/a>” “Goal Emitter”.<\/p>\n

“Goal Emitter”
\nForm Type\uff1aselect “bunny01.dae here. This selects the model you want the final form to be.

With these settings, the yellow particles converge to form the rabbit on the -X side.
\nIf you want to modify the generated form, make changes under the Generate-Form tab for “ball–rabbit emitter”.
\nIf you want to modify the converging form, makes changes to the form type under “Goal Emitter”.<\/p>\n

Next, lets input the settings for the mass particles.
\nAlthough it is not possible to input settings for mass particles with field emitters,
\nthere is a goal function in the\u00a0Inspector<\/a>\u00a0by which you can input the settings for the converging form.<\/p>\n

Lets add some drama when the particles expand.
\nWe’ll add some light coming from the center and an expanding flash.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

It’s done.
\nWhen you want to modify the speed at which the particles converge, under the “Move<\/a>” tab adjust the “Goal” Period Start and Stop values.<\/p>\n
