Particle System Renderer Mesh becomes missing when loading it from a Prefab in Editor

Visual Effects - Legacy


When a Particle prefab is instantiated the Particle System is not visible because in its Renderer module there is no Mesh. It happens only if a Mesh different from the ones included in Unity (i.e. a cube or sphere) is used

To reproduce:

1. Download attached project "" and open in Unity
2. Open "Scene" scene
3. Enter Play mode
4. Observe that in the ParticleContainer / Particle(Clone) gameObject the Particle System > Renderer > Mesh value is "None"

- This issue appears on both Windows and OSX
- In Standalone everything works as expected

Reproduced on Unity 2017.4.9f1, 2017.4.12f1, 2018.2.10f1, 2018.3.0b3 and 2019.1.0a2
Not reproduced on Unity 2017.4.8f1, 2018.1.9f2 and 2018.2.2f1
Regression on Unity 2017.4.9f1 and 2018.2.3f1
