FilterParallelFilters
A RenderNode that processes two independent filter chains — a bottom layer and a top layer — each applied to the same input, then composites their results together using a configurable blend mode. This allows you to combine two completely different filter effects on a single Game Object; for example, applying a glow to the bottom layer and a color correction to the top layer, then merging them with an add or multiply blend.
Each layer (bottom and top) runs its own ordered chain of filters in series, where the output of one filter feeds into the next. Once both chains have completed, the results are blended using the FilterBlend RenderNode according to the controller's blend settings.
If neither layer contains any active filters, the input is copied directly to the output with no modifications.
This node delegates rendering work to other RenderNodes during execution. See Phaser.Filters.ParallelFilters for the associated controller.

Public Methods
run
<instance> run(controller, inputDrawingContext, outputDrawingContext, padding)
Description:
Runs the parallel filter process. The input drawing context is passed through the bottom filter chain and the top filter chain independently, producing two separately filtered results. Those results are then blended together using the FilterBlend RenderNode with the blend mode and settings defined on the controller.
Padding is applied on the first filter in each chain only; subsequent filters in the same chain receive zero padding to avoid double-expanding the output bounds.
If no filters are active on either layer, the input is copied directly to the output unchanged.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| controller | Phaser.Filters.ParallelFilters | No | The controller that defines the bottom and top filter chains and their blend settings. |
| inputDrawingContext | Phaser.Renderer.WebGL.DrawingContext | No | The drawing context to use as the source image for both filter chains. |
| outputDrawingContext | Phaser.Renderer.WebGL.DrawingContext | No | The drawing context to render the final blended result into. May be null, in which case a new context is allocated. |
| padding | Phaser.Geom.Rectangle | No | The padding to apply around the rendered area on the first filter pass. |
Overrides: Phaser.Renderer.WebGL.RenderNodes.BaseFilter#run
Returns: Phaser.Renderer.WebGL.DrawingContext - The drawing context containing the final composited output.
