What does #pragma multi_compile_particles do?
I've noticed this in pragma in Unity's default shaders for particles but can't find any documentation as to what it does.
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#pragma fragmentoption ARB_precision_hint_fastest
#pragma multi_compile_particles
#include "UnityCG.cginc"
Can anyone shed some light on what this does?

multi_compile is for (As the name suggests) compiling multiple instances using a set of keywords, that you define. Looking at the compiled shader, the multi_compile_particles adds SOFTPARTICLES_ON and SOFTPARTICLES_OFF, so it's just Unity's own flavor of keywords for particles, containing that one. Additionally, you can toggle the keyword in quality settings.
