Caustics is a dynamic effect that generates animated underwater light patterns.
⚙ Parameters:
❶ Color — sets the color of the caustic light patterns.
❷ Speed — adjusts the animation speed multiplier for the moving light patterns.
❸ Horizontal scale — stretches caustics horizontally.
❹ Vertical scale — stretches caustics vertically.
❺ Threshold — controls the minimum brightness for caustics to appear.
❻ Sharpness — controls the edge definition of caustic patterns.
❼ Pixel size — sets pixelization strength factor.
❽ Glow intensity — creates white glow at the center of caustic lines.
❾ Glow threshold — sets the minimum value for glow to appear.
❿ Opacity variation — adds smooth opacity gradients across the caustic patterns for more natural look.
