Emit From Part Of An Object In Container

[arianrod]

Is there a way to "paint weights" when you are emitting from an object?

I have an object inside my fluid container creating a fire effect, this object purposely exits the container at a certain point in my animation. I was wondering if there is a way to emit from only part of the object so when it leaves the container the fire does not abruptly cut off at the edge of my container giving away the effect.

I also want to animate that so the part of the object that is emitting gets smaller as more of the object leaves the container. Hope that makes sense. Imagine it as a soft selection of emission growing smaller and smaller until there is no more geometry selected (or only one vertex selected). The selected part is the emitter.

Can this be done?

If I understand well what you need, this is the way I would do it:

• create a map (ramp, noise, painted, ...)  to control the emission of particles on the object's surface. Kill those particles after one frame.
• Use VoxelMaster to emit fluid from the particles (instead of the mesh).
