Unity Shader Properties Reference

The main tint colour. In URP Lit, this is replaced by _BaseColor. Sprite and UI shaders also use _Color for their primary tint.

Pipelines: Standard, Sprite, UI

// Get
material.GetColor("_Color")

// Set
material.SetColor("_Color", Color.red)

The main diffuse/albedo texture. In URP Lit, use _BaseMap instead. You can also set tiling and offset via material.SetTextureScale and material.SetTextureOffset.

Pipelines: Standard, Sprite

// Get
material.GetTexture("_MainTex")

// Set
material.SetTexture("_MainTex", myTexture)

Tangent-space normal map. The property name _BumpMap is shared across all three pipelines. Make sure the texture import type is set to Normal Map in Unity.

Pipelines: Standard, URP, HDRP

// Get
material.GetTexture("_BumpMap")

// Set
material.SetTexture("_BumpMap", normalMap)

Multiplier for normal map intensity. Values above 1.0 exaggerate the surface detail; values below 1.0 flatten it.

Pipelines: Standard, URP, HDRP

// Get
material.GetFloat("_BumpScale")

// Set
material.SetFloat("_BumpScale", 1.5f)

Range 0 to 1. Only used when there is no metallic map assigned. Set to 1 for metals, 0 for non-metals.

Pipelines: Standard, URP, HDRP

// Get
material.GetFloat("_Metallic")

// Set
material.SetFloat("_Metallic", 1f)

Range 0 to 1. Standard shader only. In URP and HDRP, smoothness is stored in the alpha channel of the metallic map or controlled by _Smoothness.

Pipelines: Standard

// Get
material.GetFloat("_Glossiness")

// Set
material.SetFloat("_Glossiness", 0.8f)

R channel stores metallic, A channel stores smoothness. When assigned, the _Metallic and _Glossiness sliders are ignored.

Pipelines: Standard

// Get
material.GetTexture("_MetallicGlossMap")

// Set
material.SetTexture("_MetallicGlossMap", metallicMap)

HDR colour. Multiply by values greater than 1 for bloom. You must also call material.EnableKeyword("_EMISSION") for emission to work.

Pipelines: Standard, URP, HDRP

// Get
material.GetColor("_EmissionColor")

// Set
material.SetColor("_EmissionColor", Color.yellow * 2f)

Texture that masks which areas emit light. The final emission is _EmissionMap multiplied by _EmissionColor.

Pipelines: Standard, URP, HDRP

// Get
material.GetTexture("_EmissionMap")

// Set
material.SetTexture("_EmissionMap", emissionTex)

Ambient occlusion texture. White means fully lit; darker values add shadowing in crevices.

Pipelines: Standard, URP, HDRP

// Get
material.GetTexture("_OcclusionMap")

// Set
material.SetTexture("_OcclusionMap", aoMap)

Range 0 to 1. Controls how strongly the occlusion map affects the final result. 0 disables occlusion completely.

Pipelines: Standard, URP, HDRP

// Get
material.GetFloat("_OcclusionStrength")

// Set
material.SetFloat("_OcclusionStrength", 0.5f)

Range 0 to 1. Only relevant when rendering mode is set to Cutout. Pixels with alpha below this threshold are discarded.

Pipelines: Standard, URP, HDRP

// Get
material.GetFloat("_Cutoff")

// Set
material.SetFloat("_Cutoff", 0.3f)

A secondary albedo texture blended on top of the main texture using UV2. Useful for adding surface variation without increasing main texture resolution.

Pipelines: Standard

// Get
material.GetTexture("_DetailAlbedoMap")

// Set
material.SetTexture("_DetailAlbedoMap", detailTex)

Secondary normal map for fine surface detail. Blended with the main _BumpMap using UV2.

Pipelines: Standard

// Get
material.GetTexture("_DetailNormalMap")

// Set
material.SetTexture("_DetailNormalMap", detailNormal)

Intensity multiplier for the detail normal map.

Pipelines: Standard

// Get
material.GetFloat("_DetailNormalMapScale")

// Set
material.SetFloat("_DetailNormalMapScale", 2f)

Range 0.005 to 0.08. Controls the strength of parallax/height mapping. Higher values create a stronger depth illusion but can cause artefacts at steep angles.

Pipelines: Standard

// Get
material.GetFloat("_Parallax")

// Set
material.SetFloat("_Parallax", 0.04f)

Replaces _Color in URP and HDRP Lit shaders. If you are migrating from Standard, update all references from _Color to _BaseColor.

Pipelines: URP, HDRP

// Get
material.GetColor("_BaseColor")

// Set
material.SetColor("_BaseColor", Color.red)

Replaces _MainTex in URP and HDRP Lit shaders. The alpha channel is used for transparency when the surface type is set to Transparent.

Pipelines: URP, HDRP

// Get
material.GetTexture("_BaseMap")

// Set
material.SetTexture("_BaseMap", myTexture)

Set automatically by SpriteRenderer.color. You rarely need to set this directly on the material; use SpriteRenderer.color instead.

Pipelines: Sprite

// Get
material.GetColor("_RendererColor")

// Set
material.SetColor("_RendererColor", Color.white)

Stencil comparison function. Default value 8 means Always. Used by Unity UI masking. Values correspond to UnityEngine.Rendering.CompareFunction enum.

Pipelines: UI

// Get
material.GetInt("_StencilComp")

// Set
material.SetInt("_StencilComp", 8)

Stencil buffer reference value. Used together with _StencilComp for UI masking. The Mask component sets this automatically.

Pipelines: UI

// Get
material.GetInt("_Stencil")

// Set
material.SetInt("_Stencil", 1)
