Same pb here after migrating a project from 2018.2 to 2018.3

[YiheChen1995]

Same problem. Any Idea how this happened?

[daxiao]

Same problem

[xooxo]

It is because Unity removed all functionality of API regarding ParticleRenderer.

[Stormwaker]

Just use Unity 2018.2 for this project. Anything newer will cause this error to appear.

As @xooxo said, ParticleRenderer has been removed. ParticleSystemRenderer is need to be used instead.

Just remove that part of the code from the OR condition and it would still works the same as the ParticleRenderer returns "true" anyway.
