Dither Texture Bias

Turns the image into a dithered version using a user-provided texture pattern. The texture’s values act as a bias added to the image before quantization, producing a stylized dither effect. Use this effect when you want full artistic control over the pattern (Bayer, blue noise, etc.).

The alpha channel is not changed by this effect.

🔑	Property	Range	Description
	Dither Pattern	🖼️	The texture used as the dither pattern. Its RGB channels act as a per-pixel bias.
	Mip Map Bias	[0, 2]	Bias applied to the mip level when sampling the dither pattern texture. Higher values select coarser mips, softening the pattern at a distance.
	Dither Amount Min	[-1, 1]	The minimum value added to each channel based on the pattern.
	Dither Amount Max	[-1, 1]	The maximum value added to each channel based on the pattern.
	Level Count	[1, ∞)³	The number of quantization levels for R, G, and B. Higher values retain more color detail.
		Smoothness	[0, 1]	Controls how soft the transitions between quantization steps are.
	🔑	Use UV Map	true / false	Enables UV-map–driven sampling of the dither pattern instead of screen-space UVs.
		UV Map	🖼️	UV map texture used to drive pattern sampling when Use UV Map is enabled.
	🔑	Use Depth Compensation	true / false	If enabled, compensates for depth when using a UV map so the pattern appears the same scale at different distances. Blends between adjacent depth bands to reduce popping and discontinuities.

Tip

• A neutral pattern (flat gray) produces no dithering.
• Bayer, blue noise, and photographic film-style patterns give very different looks.
• When using high smoothness values, subtle dithering patterns can act as a film-grain-like texture.
• You can render out a UV Map with the UV Map Renderer for the built-in pipeline, or the corresponding renderer feature for URP. There are more options for managing the scale.

Hard quantization with strong dithering.

Soft quantization with smoothness applied.
