Applies the terrain texturing information, i.e. “colors” the terrain with textures.
Note that Textures Output has a normalizer built-in. It blends layers and normalizes them so that their sum is always 1. This way the layers order matters - each upper layer will overlap the bottom ones. Consider layer masks as Photoshop layers masks.
The Background layer does not require an input since it is regarded as completely filled (a constant of 1).
To use the Textures Output you've got to create the Terrain Layer asset files: Assets -> Create -> Terrain Layer. Then these assets should be assigned in Textures Output in Layer slot.
- Opacity: the visibility factor of this layer
- Layer: Terrain Layer asset
Clicking on the properties tab will open up the layer settings so that layer parameters could be modified without opening up the layers asset.
Note that changing these values will change terrain layer asset
- Diffuse: base color Texture of the Terrain Layer
- Normal: normal information for your Terrain Layer
- Mask: The TerrainLit Shader, which is part of the High Definition Render Pipeline (HDRP) and Universal Render Pipeline (URP), uses this Mask Map Texture data. Custom Terrain shaders might also use this Texture for user-defined purposes, such as ambient occlusion or height-based blending.
- Specular: The specular highlight color of the Terrain Layer.
- Metallic: The overall metallic value of the Terrain Layer.
- N. Scale: Normal Scale of the Terrain Layer. This value acts as a scaling factor for the normal values present in the Normal Map.
See Terrain Layer documentation for more detail.
- Size: the size of the texture tile, in world units. The bigger the value - the bigger the pixels of the terrain tile are.
Note that due to better terrain welding splat prototypes the size parameter should be a multiple of the size of the terrain: if the terrain size is 1000 the proper terrain sizes are 10, 20, or 100. But with the tile size of 15 you'll get texture seams between tiles.
- Offset: the offset of the terrain tile, in world units.
