/* This shader is generated based upon the debug views you have selected.
|
||||
* The terrain function depends on this shader. So don't change:
|
||||
* - vertex positioning in vertex()
|
||||
* - terrain normal calculation in fragment()
|
||||
* - the last function being fragment() as the editor injects code before the closing }
|
||||
*
|
||||
* Most will only want to customize the material calculation and PBR application in fragment()
|
||||
*
|
||||
* Uniforms that begin with _ are private and will not display in the inspector. However,
|
||||
* you can set them via code. You are welcome to create more of your own hidden uniforms.
|
||||
*
|
||||
* This system only supports albedo, height, normal, roughness. Most textures don't need the other
|
||||
* PBR channels. Height can be used as an approximation for AO. For the rare textures do need
|
||||
* additional channels, you can add maps for that one texture. e.g. an emissive map for lava.
