Smoke systems are for particles that are emitted off of things that are
|
||
|
|
constantly changing position and orientation, like muzzle smoke coming
|
||
|
|
from a bone on a weapon, blood spurting from a wound, or particles
|
||
|
|
trailing from a monster limb.
|
||
|
|
|
||
|
|
The smoke particles are always evaluated and rendered each tic, so there
|
||
|
|
is a performance cost with using them for continuous effects. The general
|
||
|
|
particle systems are completely parametric, and have no performance
|
||
|
|
overhead when not in view.
|
||
|
|
|
||
|
|
All smoke systems share the same shaderparms, so any coloration must be
|
||
|
|
done in the particle definition.
|
||
|
|
|
||
|
|
Each particle model has its own shaderparms, which can be used by the
|
||
|
|
particle materials.
