Post-Processing

Pass Classes

• none: direct render.
• basic: lightweight post.
• standard: normal production post.
• advanced: TAA, color grading, bloom, vignette, and the highest shared runtime post budget.
• cinematic: cinematic timing and quality budget for the same shared active effects.

Effects

Supported active renderer effects include tone mapping, exposure, bloom, 3D LUT color grading, vignette, FXAA, SMAA, and TAA.

GTAO/contact shadows, depth of field, motion blur, and screen-space reflections remain policy/schema fields, but they are not active runtime tier features until both WebGL and WebGPU have pixel-proven implementations.

WebGPU uses TSL nodes for the advanced stack. WebGL uses composer passes and lower-cost fallbacks.

Camera Overrides

Cameras can override post preset, tone mapping, exposure, anti-aliasing, color grading preset/intensity, and vignette strength. This is useful for cutscenes, scoped cameras, and photo modes.

Built-In Color Grades

Built-in LUT presets are Neutral, Warm, Cool, Cinematic, B&W, and Vibrant. They are generated as 16x16x16 3D LUT textures and shared by both backends.
