Property	Description
Detail Map	Specifies a channel-packed Texture that HDRP uses to add micro details into the Material. The Detail Map uses the following channel settings: • Red: Stores the grey scale as albedo. • Green: Stores the green channel of the detail normal map. • Blue: Stores the detail smoothness. • Alpha: Stores the red channel of the detail normal map. For more information on channel-packed Textures and the detail map, see detail map.
Detail UV Mapping	Specifies the type of UV map to use for the Detail Map. If the Material’s Base UV mapping property is set to Planar or Triplanar, the Detail UV Mapping is also set to Planar or Triplanar. The Detail Map Texture modifies the appearance of the Material so, by default, HDRP applies the Tiling and Offset of the Base UV Map to the Detail Map to synchronize the Detail Map and the rest of the Material Textures. HDRP then applies the Detail Map Tiling and Offset properties on top of the Base Map Tiling and Offset. For example, on a plane, if the Tiling for Base UV Mapping is 2, and this value is also 2, then the Detail Map Texture tiles by 4 on the plane. This workflow allows you to change the Tiling of the Texture on the Material, without having to set the Tiling of the Detail UV too. To separate the Detail UV Map from the Base UV Map to set it independently, disable the Lock to Base Tiling/Offset checkbox.
- Lock to Base Tiling/Offset	Indicates whether the Base UV Map’s Tiling and Offset properties affect the Detail Map. When enabled, HDRP multiplies these properties by the Detail UV Map’s Tiling and Offset properties respectively. To separate the Detail UV Map from the Base UV Map to set it independently, disable this checkbox.
Tiling	The per-axis tile rate for the Detail Map UV. HDRP uses the X and Y values to tile the Texture assigned to the Detail Map across the Material’s surface, in object space.
Offset	The per-axis offset for the Detail Map UV. HDRP uses the X and Y values to offset the Texture assigned to the Detail Map across the Material’s surface, in object space.
Detail Albedo Scale	Modules the albedo of the detail map (red channel) between 0 and 2. This is an overlay effect. The default value is 1 and applies no scale.
Detail Normal Scale	Modulates the intensity of the detail normal map (green and alpha channel), between 0 and 2. The default value is 1 and applies no scale.
Detail Smoothness Scale	Modulate the intensity of the detail smoothness map (blue channel) between 0 and 2. This is an overlay effect. The default value is 1 and applies no scale.
