Field Value
Shader ID temporal-echo
Category Temporal
Package shaders/temporal-echo/
Temporal preLayerInput, 12 requested frames

Temporal Echo blends multiple older frames into the current image with decay and tint. It creates visible motion echoes rather than a simple blur.

Controls

Control Type Default What It Does
Echo Amount float 0.55 Mix between current frame and echo composite.
Decay float 0.72 How quickly older echoes fade.
Frame Stride float 2 Spacing between sampled history frames.
Echo Tint color Pale blue Tint and alpha applied to echo frames.

Tips

  • Increase Frame Stride for more separated echoes.
  • Lower Decay for shorter trails.
  • Use Echo Tint alpha to reduce echo strength without changing color.
  • This shader resets history after stack and bypass changes.
