<!--

|
Notice: boolean Y or N here is case-sensitive
|
|
|
|
name: The name of the shader (cannot be empty), you have to make sure
|
|
no duplicated name will be introduced, and "_skinned" word is
|
|
reserved for automatic skinned mesh shader adding.
|
|
|
|
fallback-shader: The name of the shader to be used when advanced
|
|
lighting is off, make sure that shader is loaded first
|
|
(default is empty). STK will load list of sps*.xml
|
|
files in ascending order from a directory.
|
|
|
|
transparent: If Y, than this shader will be used in transparent pass
|
|
(default N).
|
|
|
|
drawing-priority: The larger this number, the later the meshes using
|
|
this shader will be drawn. Only useful in transparent
|
|
shader where drawing order matters because of alpha
|
|
blending (default 0 which means order doesn't
|
|
matter).
|
|
|
|
use-alpha-channel: If Y, this shader is going to access alpha channel
|
|
from mesh texture layers. It's used to hint STK not
|
|
to encode colorization mask for this material using
|
|
this shader which it will overwrite the alpha
|
|
channel (default N).
|
|
|
|
use-tangents: If Y, than meshes using this shader will have tangents
|
|
and bitangents defined and you can access them in shader
|
|
(default N).
|
|
|
|
srgb: Sample mesh texture layers in srgb or not (in 6 Ys / Ns), when
|
|
advanced lighting is off, srgb will always be false,
|
|
default (Y Y N N N N), even if any texture layer is unused in
|
|
shader, you cannot skip it from the above Y / N array.
|
|
|
|
You can only specific 1st and shadow pass of shader in .xml

<!--
|
|
use-function: Specify function to be run before drawing meshes with
|
|
this shader:
|
|
|
|
alphaBlendUse will be suitable for drawing alpha blend material.
|
|
|
|
additiveUse will be suitable for drawing additive material.
|
|
|
|
ghostUse will be suitable for drawing object with translucent
|
|
effect with face culling and depth buffer writing on.
|
|
|
|
unuse-function: Specify function to be run after drawing meshes with
|
|
this shader (none at the moment).
|
|
|
|
vertex-shader: Specify the vertex shader, it will search in the
|
|
directory of the location of this xml file first, if not
|
|
found it will search in the official shader directory.
|
|
Notice: if you use #stk_include in your shader file, STK
|
|
will only search the include header in official shader
|
|
directory.
|
|
|
|
fragment-shader: Specify the fragment shader, searching rule is the
|
|
same as above.
|
|
|
|
skinned-mesh-shader: Specify the skinned mesh version of the vertex
|
|
shader, searching rule is the same as above. You
|
|
have to make sure the uniforms and the textures
|
|
used in both skinned mesh / non-skinned mesh
|
|
shader are the same.

<!--
|
|
prefilled-textures: Define the prefilled textures used in
|
|
shaders, they will be the same for all
|
|
meshes drawn using this shader.
|
|
|
|
name: Name of the texture used in shader (cannot be empty).
|
|
|
|
file: Filename of the texture, it will search using the order
|
|
in pushed texture searching directory
|
|
(cannot be empty).
|
|
|
|
srgb: Sample in srgb or not (specify in Y/N, default is N).
|
|
When advanced lighting is off, srgb will always be
|
|
false.
|
|
|
|
sampler: nearest, nearest_clamped, bilinear,
|
|
bilinear_clamped, trilinear, trilinear_clamped
|
|
and semi_trilinear are possible right now, default
|
|
is trilinear.
|

Example:

<prefilled-texture name="name_used_in_shader" file="texture.png"

srgb="Y" sampler="trilinear"/>-->

uniform-assigners: List of uniform assigners functions to be auto-run
|
|
when "use" the shader which set the uniform
|
|
variables in shader, currently there are:
|
|
|
|
shadowCascadeUniformAssigner will set the current shadow
|
|
cascade being drawn.
|
|
|
|
windDirectionUniformAssigner will set the wind direction.
|
|
|
|
zeroAlphaUniformAssigner should be used in transparent shader.
|
|
|
|
fogUniformAssigner will set 0 / 1 if fog is enabled in track.
|
|
|
|
ghostAlphaUniformAssigner will set ghost (kart) color based on sun
|
|
color of track.
|
|
|
|
You have to specify the uniform name in shader together with the
|
|
bundled uniform-assigners.
|
|
|
|
Currently you can automatically assign to uniform type int, float,
|
|
mat4, vec4, vec3 and vec2 only.
