This panel is common to all the emitters. It is used to define the emitter dimensions and the Fluid container where this emitter will create the particles.
From Collision Objects
This option works automatically and detects all objects with a → "RFCollider" and intersects the particles volume:
- Particles inside these objects will be removed.
- The "Fill" emitter is a special case, because the fill object will not be considered.
Mask surface offset
With this value it is possible to inflate or shrink the object(s) virtually to remove more or less particles.
