Question by SignalZak · Jun 16, 2016 at 11:26 PM · meshparticlesystemscaling

ParticleSystem mesh particles scaling differently in (1,1,1) scale between Simulation Space = World or Local

We are creating a Mesh particle using the default Unity plane. When we scale the GameObject holding the ParticleSystem we get different results depending on Simulation Space. Our particle size is set to 1.

Scaling a plane not in the particle system AND scaling the GameObject (mentioned above) with Simulation Space = World, we get identical scaling results. Scaling a 1x1 plane by 2 results in a 2x2 plane.

When we change the Simulation Space = Local, scaling that GameObject by 2 results in a 4.5x4.5 plane.

The Scaling Mode does not affect this behaviour, only the Simulation Space value.

Is this expected behavior? If so, where is it getting this extra multiplier on our scale?
