Objects cannot only be filled You can fill objects with particles, but it is also possible to or cover their surface with a regular particle matrix:
- Add a "Fill" emitter and drag the object meant to be covered with particles, to the emitter's "Body" slot.
- Set "Particle Distribution" to "Particle Layer".
- The emitter's "Emission" tab collapses and shows a reduced parameter set.
- In order to get a more or less dense particle distribution increase/decrease the fluid container's "Resolution".
- If the particle layer is not updated automatically, reset the scene: go to the timeline's last frame, and then back to frame 0.
