Rainbows

Rainbows simulate prismatic lens artifacts with spectral colors. Use them for dreamy, magical, or stylized optics.

Where to Find It

• Open the TrueSKY panel -> Effects.
• In Layer Stack, click + and choose Rainbows.
• Select the layer to edit its settings.

Panel Layout

• Opacity: Master blend for the layer.
• General Settings: Strength, thresholds, and saturation.
• Shape: Symmetry and brightness clamps.
• Distortion: Warping, dispersion, and translation.

Controls

General Settings

• Opacity: Blends the effect with the original image.
• Strength: Overall rainbow intensity.
• Light Threshold: Brightness cutoff for rainbow generation.
• Color Modulation: Varies hue distribution in the rainbow.
• Light Saturation: How vivid the colors appear.

Shape

• Rotation Samples: Quality of rotational symmetry (higher is smoother).
• Rotation Iterations: Number of rotation layers for complexity.
• Clamp Brightness: Enables Brightness Maximum.
• Brightness Maximum: Clamps peak brightness.

Distortion

• Amount: Threshold for distortion trigger.
• Distortion: Intensity of warping.
• Pull/Push: Radial push or pull effect.
• Dispersion: Chromatic separation strength.
• Fit: Aspect correction.
• Translate
• Offset: Starting point for translation.
• Amount: Intensity of positional shift.
• Direction: Angle of shift.

Tips / Workflows

Typical Use

Keep Strength modest for subtlety. Increase Rotation Iterations for complexity, and push Distortion only in stylized shots.
