Particle Layers

CActionFactoryParticleSpawnerBase	Particle spawner, emits particles in the world
CActionFactoryWithChilds	Folder, contains multiple child layers, allows to group them and schedule them with a common delay / repeat count / repeat mode.
CActionFactorySound	Plays a sound.
CActionFactoryDecalSpawner v1.5.5	Experimental, Sticks a decal on the scene. Useful when combined with a particle collide trigger.
CParticleSpatialDescriptor v1.8.0	Special type of storage layer. Gives access to spatial queries from particle scripts, enabling particle/particle interactions between different layers and effects.

Particle Evolvers

Evolve state	Root node that contains all the evolvers. In the future we might handle multiple evolve states and the ability for particles to switch from one state to another based on a script-based condition.
CParticleEvolver_Spawner	Used to create trails. this evolver will spawn other particles
CParticleEvolver_Field	Binds a curve to a particle property
CParticleEvolver_Script	Runs a custom script at each evolve step
CParticleEvolver_Rotation	Updates particle rotations, given a rotation speed
CParticleEvolver_Damper	Damps any field over time
CParticleEvolver_Physics	Handles velocity / gravity / acceleration / collisions. main evolver for moving particles around.
CParticleEvolver_Collisions	Handles collisions with the scene or a custom shape or shape collection.
CParticleEvolver_Flocking	Adds autonomous flocking behaviours to the particles
CParticleEvolver_Containment	Constrains the particles to a volume
CParticleEvolver_LimitDistance	Constrains particles to a certain distance-range from a set of shapes.
CParticleEvolver_Projection	Projects particles on a shape's surface.
CParticleEvolver_FlipBook	Simplifies the use of animated textures
CParticleEvolver_Localspace	Runs a list of child evolvers in the effect instance's localspace.
CParticleEvolver_Attractor	Gravitationally attracts particles to a shape's surface.
CParticleEvolver_SpatialInsertion v1.8.0	Inserts a particle inside a spatial layer.

CParticleRenderer_Billboard	Renderer particles as billboards/sprites. handles texture atlases, various billboarding & alignment modes
CParticleRenderer_Light	Transforms particles into dynamic lights that light the scene
CParticleRenderer_Mesh	Renders particles as meshes
CParticleRenderer_Ribbon	Renders particles as continuous ribbons-trails
CParticleRenderer_Sound v1.7.0	"Renders" the particles as sound sources.

CParticleSamplerCurve	Samples a curve, from 1 to 4 dimensions. like the CParticleEvolver_Field
CParticleSamplerDoubleCurve v1.5.4	Samples a double-curve, from 1 to 4 dimensions.
CParticleSamplerShape	Samples a shape, can be boxes, spheres, cylinders, capsules, cones, or meshes
CParticleSamplerAnimTrack	Sweeps and rotates a shape sampler along a user-defined path
CParticleSamplerTexture	Samples a texture, with various optional wrap & filter modes
CParticleSamplerProceduralTurbulence	Samples a procedural turbulence field, useful for making convincing turbulence-like effects without a fluid simulation
CParticleSamplerSpectrum	Samples an audio frequency spectrum, useful for making particles react to music/sounds
CParticleSamplerText v1.7.0	Samples either the ascii codes of a text (you can use this to index a texture atlas), or positions on a text with a custom .TTF font.

Particle fields	Contains the list of properties (fields) of a particle
Particle events	Contains the list of events the particle can trigger
Effect attributes	Contains the list of properties of the whole effect. This is what's used by the game to control and modify the effect at runtime.

Main page: Editor backdrops
These are editor-only edition helpers, they will not appear in the final effect.

CNEdEditorBackdrop_Audio2D	Plays back a non-spatialized audio track.
CNEdEditorBackdrop_Brush	Draws a color gradient (takes the camera orientation into account)
CNEdEditorBackdrop_Image	Draws a texture in the backdround
CNEdEditorBackdrop_Video	Plays back a video in the backdround
CNEdEditorBackdrop_Cubemap	Draws an environment cubemap (takes camera orientation into account)

CNEdEditorBackdrop_Sound3D	Plays back a 3D-spatialized audio track
CNEdEditorBackdrop_Model3D	Draws a 3D FBX model in the scene (can be animated). Particles can collide with these.
CNEdEditorBackdrop_Grid v1.9.0	Draws a 3D grid. Particles can collide with these.
CNEdEditorBackdrop_Effect	Inserts and plays an effect in the scene. Can be the effect that's currently being edited, or another effect.
CNEdEditorBackdrop_Alembic	Draws and runs an alembic scene (can be animated). Particles do NOT collide with these.
CNEdEditorBackdrop_Light	Inserts a light in the scene.
CNEdEditorBackdrop_Camera	Experimental Inserts a camera in the scene.
CNEdEditorBackdrop_Text v1.9.0	Displays 3D text in the scene.
CNEdEditorBackdrop_Wind v1.9.0	Injects wind sources into the particle simulation.
