Particle simulators have two properties in addition to the standard Layer materials.
- Billboarded lights – lights a 3D particle effect as if the individual particles are all facing towards the light. This can be useful if you want an evenly lit particle effect.
- Billboarded shadows – shadows are cast from a 3D particle effect as if the individual particles are all facing towards the light. This can be useful if you want shadows to appear more solid.
