filters-and-postfx

To apply post-processing filters in Phaser 4, enable WebGL and activate filters on the specific game object. You can then use the FilterList and Controller components to add effects like glow, blur, and color matrix adjustments for enhanced rendering.

Internal filters in Phaser 4 apply effects directly to individual game objects within their local context, while external filters operate in screen-space on cameras. Choosing between them affects rendering performance and how you chain visual effects like glow and blur.

Yes, you can chain multiple visual effects like glow, blur, and color matrix on a single Phaser 4 sprite. The FilterList component manages these sequences to ensure predictable and performant rendering across object-local contexts.

Yes, Phaser 4 post-processing strictly enforces WebGL usage. This requirement ensures that visual filters and effects like glow, blur, and color matrix adjustments perform predictably and render correctly on targeted scenes and game objects.

Phaser 4 visual filters may not render if WebGL is inactive or if filters are not explicitly enabled on the specific game object. You must properly configure the FilterList and Controller components to trigger the post-processing workflow.
