CScatter is Corona's dedicated scattering system. It can be used to efficiently produce effects like grass, hair, forests, carpets. CScatter can be used in combination with CProxy objects.
To scatter objects:
1. Go to Create > Geometry > Corona and create CScatter anywhere in your scene
2. Pick distribution object or objects
3. Pick instanced (scattered) objects
4. Adjust parameters
In CScatter, you can use density and scale maps for scattered objects.
Note: creating large amounts of instanced objects may have impact on viewport performance. It is advised to decrease the amount of displayed objects under "Display" rollout in CScatter parameters.
