Implementes a terrain renderer as well as some associated features.

• Terrain rendering component
• Vegetation scattering support using instancing
• A spline renderer that can optinally be aligned to the height map (for roads etc)

Add terrain component an entity, setup heightmap and material. If using a height field collider then the entity should be offset (0.5, 0, 0.5) from the origin. Material can be setup using blend layers or whaterver you like.

Add spline component, then add child entities, these children will be used as control points for the spline. Terrain can be set on the spline component if it should be aligned to the terrain heightmap.

Add vegetation, model and instancing component. Note that instancing has to be added after the model component. Link vegetation to terrain and setup the various properties, splines can be added to the blocking list, this will prevent vegetation from spawning on it.

Duplicate the entity and change the model and settings for any other vegetation types that you want to setup.

• Only support short height conversion type on the heightmap asset, anything else will cause a null reference exception
• Uses a hidden model component, this means that there must be no model component assigned to the entity with the terrain component as only on model component per entity is supported
• No LOD, so probably only suitable for small terrains
• Exception when loading in Game Studio, just press Resume until it goes away
• Vegetation and spline rendering unstable in Game Studio, sometimes stops working when assemblies are reloaded
