A 3D trail add-on for the Godot engine

ProtonTrail - 3D Trail addon for Godot

Overview

• 3D trail custom node for Godot Engine
• Generated at runtime
• Adjustable resolution
• It's just a mesh so you can apply your own materials on it

How to use

• Clone the repository to your addons folder
• Go to Project settings > Plugins and activate the ProtonTrail plugin
• Add a ProtonTrail node to your scene
  • It should automatically create two new child nodes Top and Bottom
• You should have a setup similar to this :

• The Top and Bottom nodes define the width of the trail. When these nodes move through space, the trail is generated between them.

Parameters

• Resolution
  • Defines the geometry density.
  • Higher values means more vertices generated when the emitter moves.
  • Reasonable values are roughly between 6 and 15.
• LifeTime
  • Defines how long the trail is.
  • Higher values means a longer trail.
• Smooth
  • How much smoothing to apply to the trail.
  • Set it to 0 to disable it.
  • This is especially usefull on fast moving objects.
• Invert UV X
  • Flip the UV coordinates on the X axis.
  • By default, the left side of the texture is where the trail emitter is.
• Invert UV Y
  • Flip the UV coordinates on the Y axis.
• Emit
  • Generates a trail when the emitter moves.
  • If disabled, all previously generated trails will still be rendered, but no new geometry will be generated
