VFX

Overview

VFX objects enhance a game’s visual elements, adding immersion and excitement. They can be applied to parts, characters, and environments, enriching gameplay experiences.

Types of VFX

VFX	Description	Examples
ParticleEmitter	Generates particles	Fire, smoke, explosions, magic, water droplets, etc.
Beam	Connects two points	Lasers, electricity, energy beams, etc.
Trail	Trail (trajectory) effect	Speed boosts, magic trails, bullet traces, etc.

ParticleEmitter

Properties

Property	Description
Acceleration	Direction and magnitude of acceleration
Brightness	Particle brightness
Color	Particle color
Light Emission	Determines how much light the particle emits
Orientation	Defines particle rotation direction Facing Camera : Aligns the particle to always face the player's camera (the direction the player is looking) Facing Camera World Up : Faces the camera but the particles maintain an upward orientation based on world Y-axis Velocity Parallel : Particles align parallel to the velocity vector. Velocity Perpendicular : Particles align perpendicular to the velocity vector.
Size	Particle size
Texture	Texture Id for the particle (ovdrassetid://number format)
Transparency	Adjusts particle transparency
Drag	Air resistance effect
Enabled	Toggles particle activation
Emission Direction	Determines the direction of particle emission Top : Emits upwards Right : Emits to the right Back : Emits backward Left : Emits to the left Bottom : Emits downward Front: Emits forward
Life Time	Duration before a generated particle disappears
Rate	Number of particles generated per second
Rot Speed	Rotation speed
Rotation	Initial rotation angle
Speed	Initial velocity
Spread Angle	Angle range for particle emission
Squash	Compression effect applied to particles
Flipbook Layout	Defines the animation texture sheet layout (rows and columns) None : No flipbook animation Grid 2x2 : Divides the texture into a 2×2 grid Grid 4x4 : Divides the texture into a 4×4 grid Grid 8x8 : Divides the texture into an 8×8 grid
Flipbook Framerate	Frame rate of the animated texture
Flipbook Mode	Animation playback mode Loop : Repeats animation from start to finish One Shot : Plays animation once Ping Pong : Plays forward, then reverses back Random : Plays frames in random order
Flipbook Start Random	Starts animation from a random frame
Shape	Defines the initial particle emission shape Box : Particles spawn within a box-shaped area Sphere: Particles spawn within a spherical area Cylinder : Particles spawn within a cylindrical area Disc : Particles spawn within a disc-shaped area
Shape in Out	Sets the movement pattern of particles during emission and dissipation Outward : Particles are emitted outward from the shape area One : Particles are emitted inward toward the shape area
Shape Style	Sets the style of particle emission Volume : Particles are emitted from random positions within the shape's volume Surface : Particles are emitted only from the surface of the shape

Script Feature

ParticleEmitter

Beam

An object that connects between two Attachments. They are automatically connected when you specify a start and end point, and are used to create effects like lasers, electricity, and energy beams.

Properties

Property	Description
Color	Beam color
Enabled	Activation status
Color Texture	Beam color texture
Color Texture Length	Color texture repetition length
Color Texture Speed	Color texture movement speed
Alpha Texture	Beam transparency texture
Alpha Texture Length	Transparency texture length
Alpha Texture Speed	Transparency texture movement speed
Transparency	Transparency
Attachment 0	Beam starting point
Attachment 1	Beam ending point
Start Curve	Curvature of the beam's start section from Attachment 0 to Attachment 1
End Curve	Curvature of the beam's end section from Attachment 0 to Attachment 1
Width 0	Beam starting width
Width 1	Beam ending width
Facing Vector	Direction vector the beam is facing

Script Feature

Beam

Trail

An object that creates a trail (trajectory) effect left behind by a moving object. Used to create effects such as sword effects, speed boosts, magic trajectories, and bullet trails.

Properties

Property	Description
Color	Trail color
Color Texture	Trail color texture
Color Texture Length	Color texture repetition length
Color Texture Speed	Color texture movement speed
Alpha Texture	Trail transparency texture
Alpha Texture Length	Transparency texture length
Alpha Texture Speed	Transparency texture movement speed
Transparency	Transparency
Enabled	Activation status
Lifetime	The amount of time that a trail is kept after it is created (in seconds)
Width	Default width
Width Scale	Defines how width changes over time
Offset	Repositions the Trail in the X, Y, and Z directions

Script Feature

Trail

Properties Supported by the Curve Editor

Properties that can be edited with the Curve Editor are marked with a … button next to them. Clicking this button opens the Curve Editor, where you can intuitively plot the change in value of that property in graphical form.
