PYROCLUSTER

Radius, Radius 2



The Radius 2 parameter is only available when Type is set to Torus.

Radius and Radius 2 define the

size of the puffs. Their exact

meaning depends on the shape

of the puffs.

Radius

Radius 2

Sphere

Cylinder

Box

Torus

These parameters set the maximum size of the puffs. The meaning of the values

depends on the shape chosen using the Type drop-down list. The puffs will usually be
smaller than this size when rendered because fractal noise is applied during rendering
that removes parts of the puffs to literally carve out a realistic, complex shape.

Use Hemisphere, Hemisphere



The Hemisphere parameters are only available when Type is set to Sphere.

If you have chosen a spherical shape for the puffs and you don’t want to use a
whole sphere, enable the Use Hemisphere option and type the percentage of the
sphere that you want removed into the Hemisphere box.

Use Particle TM



For this function to work, the particles must be rotating, i.e. have a non-zero
Rotation value on the emitter’s Particle page.

If you enable this option, PyroCluster will use the particle’s transformation matrix to
calculate the rotation of any puff or atmospheric effect.

Use Auto Rotation

Here, all information is based on

the velocity vector only. A particle

spinning in one place (no movement)

will still result in a static, spherical

puff. To match the PyroCluster puffs

to the particle movement or rotation

or both, ensure that the particles

truly move through space. Rotation

without movement makes no sense

for cloud systems.

If you enable this option PyroCluster will analyze every particle and the velocity vector
of every particle. The puffs will acquire the rotational change of every single particle
in the attached particle system.
