Illumination page
PyroCluster effects can be 
lit in several ways using the 
options on this page.
The illumination of atmospheric effects is one of the keys to successful and believable 
animation. Without light, there’s nothing to see.
The type of illumination used 
can dramatically change the look 
of a PyroCluster effect.
Use Illumination off.
Diffuse lighting.
Ray Angle lighting.

Mode
Diffuse
 
Use Diffuse lighting for clouds and smoke effects.
Use this option if you want to employ a diffuse lighting method. The examples 
above  show  the  difference  between  the  different  illumination  models.  Diffuse 
lighting spreads the light within the puff itself.
Ray Angle
 
Use Ray Angle lighting for fire and smoke effects.
Enable this option if you want to use the Ray Angle lighting method. The example 
on the right, above, shows how Ray Angle illuminates according to the line of sight 
to the light source.
