Methods

Name	Description
`addLayer` ()	Adds a new layer
`bind` (state)	Binds the material and sets all relevant graphics state for rendering.
`isTransparent` ()	Returns true if the material is transparent (blend mode is not opaque).
`setSprite` (uvSize, uvPosition)	Sets the sprite UV size and position for texture atlases.
`textureOffset` ()	Gets the current texture offset (UV translation).
`textureOffset` (v)	Sets the texture offset (UV translation).
`textureScale` ()	Gets the current texture scaling (UV scaling).
`textureScale` (s)	Sets the texture scaling (UV scaling).
`unbind` (state)	Unbinds the material and restores graphics state.

Description

The TerrainMaterial class manages splat maps, texture layers, and blending parameters used for physically-based terrain shading.
