Blood Spray is a Pro-only effect, available in Ignite Pro. 
Creates a spray of blood that jets out from the center point. The effect can also simulate the blood impacting on a surface.
Particle generation
These properties determine when the spray begins, its duration and its total density.
A longer duration will result in a thinner spray unless the number of particles is also increased.
Particle birth properties
The angle, speed and size of the spray are set using these properties.
Simulation
By default the spray is pulled down by gravity. The strength of this gravity can be adjusted.
The collision plane can be used to simulate the effect of the spray hitting a flat surface.
Appearance
The color of the spray is set here. The spray has two colors, which are used to create the illusion of depth.
Illumination
The illusion of depth can be adjusted using the illumination properties.
Motion blur
The blood spray effect can receive automatic motion blur.
