Fix height sampling on some terrain sizes, add tooltips to convars, fix server compile errors, set terrain prefab to craggy, set default global lod scale to 2
Add ConVar to use MeshColliders for terrain cells, add editor buttons to create mesh colliders, clean up unused code, and put debug info behind flags.
Clean up editor, fix LOD extent validation, fix editor defaults causing 0 LOD extents, and set new defaults
Terrain cell mesh colliders with separate cellsize from rendering
Terrain mesh collision cells wip
- TerrainHoles support
- Add compute blit when using R16 format
- Only create R16 map when enabled
- Change low res heightmap to use full uint16 range
- Initialise groupthread min and max at texture bounds to fix border values
Terrain collision update tests
- Implement CPU heightmap functions in GPU compute (HeightMapApply), should remove need for map sync
- Profile tests for AddHeight and SetHeightsDelayLOD using a limited texel area
- Add option to use terrain R16 maps, and the active terrain render texture
- Use R16 UAV heightmap for compute and terrain vertex shader
- Improve camera culling by including min/max height of cell
Add alternate slanted grid topology option
Fix culling radius calculation
Fix LOD scaling cell positions for culling
Testing changing terrainData heights with different apply methods, and using terrainData heightmap RenderTexture
- Swap terrain convar lodFactor with lodGlobalScale
- GlobalScale effects cell counts between each LOD level
- Add LOD cell extent sliders for each individual LOD level
- Simplify instance offsets calc
- Adjust culling for new terrain cell sizes
- Fix lod border cells, and negative cells
- Change mesh master to only 3 submeshes
- Change instance offsets and arguments for new approach
- Culling toggle in editor
- Fix issues with cell offsets
- Fix grid offsets with negatives
- Change dispatch thread size
Split grid sideblocks to simplify thread to coords
Nested grid changes:
- Add scale to instance data
- Move rotation float2 to uint
- Handle finding grid coords in nested grid with thread id
- Find LOD using precomputed offsets instead of distances
- Adjust grids by offset from LOD0 grid

Fix mesh creation with border meshes
Calculate instance offsets when LOD factor is updated
Combine per LOD compute into singular dispatch
Calculate cellsize based on vertex count and texels per unit
