PyroCluster is a real volume tracer that uses advanced volume calculations.
Unfortunately, atmospheric effects usually take a while to render. You must take
care when using several light sources in a PyroCluster scene. On the one hand, one
or two lights are all that you need to light the effect. On the other hand, it is virtually
impossible to light an entire scene using just two lights.

So that you can choose which lights in your scene will influence any PyroCluster
effects, in the Attribute manager each light source has two options on the Scene
page: PyroCluster Illumination and PyroCluster Shadow Casting.
effects, in the Attribute manager each light source has two options on the Scene
page: PyroCluster Illumination and PyroCluster Shadow Casting.
These are global settings; all PyroCluster effects in a scene will be influenced;
other objects in the scene are not affected by these settings.
You can choose how
each light source will
affect PyroCluster puffs.
To describe the effect of light exclusion, we’ll use the simple scene above. The scene
contains two light sources both pointing towards the Pyrocluster effect, and both set
to cast shadows. Disabling PyroCluster Illumination is useful when you’re trying to
control just the lighting of the PyroCluster effect, leaving shadows as they are. With
both options disabled we see the effects of other light sources.
