Randomize
The Random Seed slider and Randomize button are presented whenever a Fusion node relies
on a random result.
Two nodes with the same seed values will produce the same random results. Click the
Randomize button to randomly select a new seed value, or adjust the slider to manually select a
new seed value.
Elasticity
Elasticity affects the strength of a bounce, or how much velocity the particle will have remaining
after impacting upon the Bounce region. A value of 1.0 will cause the particle to possess the
same velocity after the bounce as it had entering the bounce. A value of 0.1 will cause the
particle to lose 90% of its velocity upon bouncing off of the region.
The range of this control is 0.0 to 1.0 by default, but greater values can be entered manually.
This will cause the particles to gain momentum after an impact, rather than lose it. Negative
values will be accepted but do not produce a useful result.
Variance
By default, particles that strike the Bounce region will reflect evenly off the edge of the Bounce
region, according to the vector or angle of the region. Increasing the Variance above 0.0 will
introduce a degree of variation to that angle of reflection. This can be used to simulate the
effect of a rougher surface.
Spin
By default, particles that strike the region will not have their angle or orientation affected in any
way. Increasing or decreasing the Spin value will cause the Bounce region to impart a spin to
the particle based on the angle of collision, or to modify any existing spin on the particle.
Positive values will impart a forward spin, and negative values impart a backward spin. The
larger the value, the faster the spin applied to the particle will be.
Roughness
This slider varies the bounce off the surface to slightly randomize particle direction.
Surface Motion
This slider makes the bounce surface behave as if it had motion, thus affecting the particles.
Surface Motion Direction
This thumbwheel control sets the angle relative to the bounce surface.
