Properties
alpha Mode
clear
Clear the target before drawing. Set false when several viewport passes share a target.
Readonlyengine
Engine captured at task creation.
Optionalexecution Enabled
Runtime frame-graph execution gate, default true. When false, the frame graph keeps the task recorded
and its resources alive but skips every pass or built-in execute() call for that frame. This is
independent from any task-specific enabled state whose disabled transition may still execute work.
exposure
Readonlyname
output Texture
Optional Readonlyscene
Owning scene for scene-bound tasks. Undefined for scene-less standalone frame graphs.
source Sampling Mode
source Texture
target Texture
threshold

Methods
dispose
-
Free all GPU resources owned by this task.
Returns void
Optionalexecute
-
Optional fast path for built-in tasks that execute without recorded Pass objects.
Returns number
record
-
Called once when the frame graph is built. Must complete synchronously.
Returns void
update Uniforms
-
Recompute and upload the pass's uniform buffer from current settings. Call after mutating effect parameters.
Returns void
A post-process task that keeps only pixels whose luminance exceeds
thresholdand zeroes the rest.
