Enumeration ParticleBlendingMode

Adds the background and final particle color together. This is useful for glow effects, like those you might use for fire or magic spells.

Custom blending

Multiplies the final particle color with the background color. This is useful for portals and light-rays.

Default rendering mode

Subtracts the final particle color from the background, which darkens the particles against the background. This is useful for foggy effects, like those you might use for steam, or thick black smoke.
