The sepia effect applies a warm, brownish tone to your scene, creating a vintage photograph appearance.

Usage

import { NgtpEffectComposer, NgtpSepia } from 'angular-three-postprocessing';

@Component({
  template: `
    <ngtp-effect-composer>
      <ngtp-sepia [options]="{ intensity: 0.5 }" />
    </ngtp-effect-composer>
  `,
  imports: [NgtpEffectComposer, NgtpSepia],
})
export class SceneGraph {}

Options

Property	Type	Default	Description
intensity	number	1.0	Intensity of the sepia effect (0-1)

Example: Vintage Photo Look

@Component({
  template: `
    <ngt-mesh>
      <ngt-torus-geometry *args="[1, 0.4, 16, 32]" />
      <ngt-mesh-standard-material color="white" />
    </ngt-mesh>

    <ngtp-effect-composer>
      <ngtp-sepia [options]="{ intensity: 0.8 }" />
      <ngtp-vignette [options]="{ darkness: 0.5 }" />
      <ngtp-noise [options]="{ opacity: 0.05 }" />
    </ngtp-effect-composer>
  `,
  imports: [NgtpEffectComposer, NgtpSepia, NgtpVignette, NgtpNoise, NgtArgs],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class SceneGraph {}

Tips

• intensity: 1.0 applies full sepia effect
• intensity: 0.5 creates a subtle warm tint
• Combine with NgtpVignette for classic old photo look
• Add NgtpNoise for film grain texture
• Works well with NgtpBrightnessContrast for faded vintage appearance
