BP VFX ENV BaseActor

The BP_VFX_ENV_BaseActor is the base Blueprint Actor that all other VFX Blueprints inherit from.
It implements shared functions used by child Blueprints and provides events to start and stop effects from other Blueprints or Sequencer.

All Blueprints expose the events Activate VFX and Deactivate VFX. These events can be called from other actors or from Sequencer.
To keep an actor inactive until it is explicitly triggered, uncheck the Active checkbox (Active = False).

Bounds

All child Blueprints also use a unified bounds system to ensure correct culling. Bounds parameters are located under the Bounds section of the Details panel for each child Blueprint:

  • Bound Size — The size of the bounds in world coordinates (not affected by the actor’s scale).
  • Bound Offset — Offset of the bounds center (not affected by the actor’s scale).
  • Visualize Bounds — Checkbox that enables debug drawing of the bounds in the viewport.
  • Bounds Draw Duration — Duration (in seconds) that the debug bounds are rendered in the viewport.
  • Line Color — Color of the debug-drawn bounds outline.
