Particles
Particles are the visible component of a VFX, and are created exclusively by emitters. They are similar to emitters in that they can be positioned in 3D space.
There are several types of particles:
- Decal
- Decal Ring
- Disc
- Laser
- Light Model
- Line
- Model
- Parameter
- Polygon
- Powder (used for small particles, such as the dust which some weapons create)
- Windmill
- Quad (a 1x1 square)
Particles can have textures mapped onto them using several different types of nodes (covered later).
Sometimes, a particle does not require complex animations, and can use the
SimpleAnimations
node instead (in order for it to work, the SimpleAnimationsEnabled
attribute must be True
) This is often used for Powder
particles, which often have very basic animations due to their size and number.There are several types of texture nodes which can be applied to a particle. Most texture nodes will have a
TextureIndex
. This determines which texture will be used as a color, normal map, etc. TextureColor1
is especially important as it has MaskTextureIndex
, which determines which parts of the particle will be transparent.Most texture nodes will also have a
UVSetIndex
(UV Sets are discussed later).UV Sets are contained within particles, and are used to manipulate textures. This primarily involves scaling, rotating, and offsetting a texture. For example, most aura or fire VFXs will use a UV Set to animate a texture so that it "scrolls" across the particle, creating the illusion of a moving flame or energy aura.
