# TerrainHLOD
|
|
|
|
TerrainHLOD takes a Terrain as input and converts it to a HLOD Mesh.
|
|
|
|
## Common
|
|
|
|
|
|
|
|
**Source**: Set the source TerrainData to generate the HLOD.
|
|
|
|
**Destroy terrain**: The original terrain will be deleted on build when you check this.
|
|
It is deleted only the Terrain when using same TerrainData on same scene.
|
|
|
|
**Chunk Size**: Sets the size of the terminal node in HLOD. Nodes are
|
|
split into quadtrees until they are smaller than this value at full
|
|
size.
|
|
|
|
**Border Vertex Count**: For each side of a terminal node terrain
|
|
patch, we allocate this number of regularly spaced vertices. As we
|
|
combine terrain patch for lower LOD levels, although we can simplify
|
|
and reduce vertex count for inner vertices, we must preserve vertices
|
|
at the edge to avoid seams. So for example if we have 3 LOD levels and
|
|
Border Vertex Count is 256, terminal node have 256

## Simplifier
|
|
|
|
See section [Simplifier](Simplifier.md).
|
|
|
|
## Material
|
|
|
|
Set up the material to be used for the baked TerrainHLODMesh. Note
|
|
that we bake the Splat System into single textures for our
|
|
TerrainHLODMesh material.
|
|
|
|
|
|
|
|
**Material:** Specifies the Material to be used for the
|
|
TerrainHLODMesh.
|
|
|
|
**Size:** Specifies the size at which the texture will be baked.
|
|
|
|
**Texture properties:** We'll bake 3 textures for the material:
|
|
Albedo, Normal, and Mask. Mask texture's R and G channel contains
|
|
roughness and specular parameter. This property decides which material
|
|
property these textures are set to.
