+### Render Layer Changes
+
+Layer Changes allow you to change what layer a block renders on.
+
+#### Representation
+
+```java
+layer.solid=<blocks>
+layer.cutout=<blocks>
+layer.cutout_mipped=<blocks>
+layer.translucent=<blocks>
+```
+
+#### Example
+
+```
+# Change Stone To A Translucent Block
+layer.translucent=stone
+```
+
+#### Default
+
+No change. If this option is not present then the blocks render in the way that mojang has chosen.
+
+#### Implementation Support
+
+* ❌ ShadersMod
+* ✔️ OptiFine
+* ✔️ Iris
+
+Note: Optifine Only Has Partial Support

+## Custom Textures
+
+### Registering
+
+Custom Textures allow you to create a custom texture2D sampler, allowing you to use them.
+
+#### Representation
+
+```java
+customTexture.<name> = <path>
+```
+
+Paths use the root folder of shaders
+
+#### Example
+
+```
+# Addded A LUT for Sunlight with the texture in shaders/textures
+customTexture.sunlightLUT = textures/sunlightLUT.png
+```
+
+#### Usage
+
+```
+#In an fsh file, using the example above
+uniform sampler2D sunlightLUT; // The Sunlight LUT
+
+#Gets the color at 0.5, 0
+vec4 color = vec4(texture(sunlightLUT, vec2(0.5, 0)), 1.0)
+```
+
+#### Default
+
+No change. If this option is not present, then no custom samplers are present.
+
+#### Implementation Support
+
+* ❌ ShadersMod
+* ✔️ OptiFine
+* ✔️ Iris
+
+Note: Optifine has diffrent syntax.
