			== Quality Settings ==
			[[File:Quality Settings.jpg]]

			=== Maximum Fur Layers ===
			This setting only affects the quality of the shader when viewed up-close (ie. hugging/snuggling/sticking-your-nose-in-a-mirror distance). At a more typical conversational distance the shader is usually rending around 8-10 layers, regardless of this setting. Each time the distance doubles the number of layers drops by half, and when the number of layers drops below 1 the fur stops rendering.

			Note that the 32-layer option has a moderate performance hit of about 5% versus the 24-layer option, even when rendering only 8-10 layers. Because of this, the 24-layer option is the default, and is recommended for most uses.

			The performance hit of using 24-layers instead of 16 is much less, roughly 1-2%. However, if your avatar has a high poly count, you may want to limit the layers to 16 anyway, to reduce stuttering on lower end GPUs when hugging/snuggling/sticking-your-nose-in-a-mirror.

			The Lite version of the shader has a fixed limit of 16 layers, and does not display this option.

			=== Quality Settings ===
			The shader detects where it is rendering (in VR, on desktop, in a VR Chat screenshot, etc...) and then uses the options in this section to choose a target layer density. For example, "Slow 300" will render at double the resolution of "Fast 150".

			Most of the information that allows the shader to determine where it is rendering is provided by VR Chat. However, there are a couple of exceptions.

			Detecting "Unity Editor Quality" requires that the shader's GUI has been opened at least once since starting Unity, until then it will render at "Desktop Quality".

			Differentiating between the "Camera Viewfinder", "Camera Photo", and "Stream Camera" depends upon checking the target Y resolution. Resolutions of 1080, 1440, 2160, or 4320 will be assumed to be a "Camera Photo", a resolution of 720 will be assumed to be the "Camera Viewfinder", and everything else will be assumed to be the "Stream Camera".

			Note: In a future update, most of these options will be removed and replaced with a simplified "Maximum Range" slider.

			UV Discard is an advanced feature that allows sections of a mesh to be discarded on-the-fly. This can be used to hide clothing or other accessories.

			''The mesh must be pre-configured in Blender'' (or any other 3D software) so that the sections to be selectively discarded use specific UV coordinate ranges.

			Typically, all vertex UV coordinates are located between 0-1. These coordinates are then used to determine where to take any texture samples.

			However, if a UV coordinate is outside of this 0-1 range, the texture samples will still work because the GPU will tile the textures. For example, a sample taken from location (1.5, 1.5) will be return the same result as one taken from (0.5, 0.5).

			UV Discard detects when this happens, and if desired it can then discard the vertex so that it does not render.

			=== Discard UV ===
			Most meshes only use the default UV coordinates of UV0. However, it is possible to have up to 4 sets of UV coordinates. This option determines which set to use for the purposes of UV Discard.

			=== UV Discard Grid ===
			Each of the 16 toggles in this grid represents the starting address of a UV coordinate range. The columns represent the starting U coordinate, and the rows represent the starting V coordinate.

			For example, the bottom-left toggle represents the range of (0.0, 0.0) - (1.0, 1.0), which is the default range that most meshes use. For most meshes (ie. meshes that haven't been set-up to use non-standard UV coordinates), enabling this toggle will result in the entire mesh being discarded.

			The highest supported UV range is the upper-right toggle, which represents the range of (3.0, 3.0) - (4.0, 4.0).

			==Skin - Physically Based Shading==
			[[File:Skin PBS.jpg]]

			===PBS Skin Strength===
			To maximize speed, the shader's fur layers use many lighting calculation shortcuts and approximations. The skin, however, can use proper physically based shading, which allows for more realisitic and accurate lighting effects.

			Setting the PBS Skin Strength to 0 will cause the shader to use the same simplified calculations for the skin, which may be desireable in order to match the appearance of the skin and the fur in all lighting conditions.

			===PBS Skin Depth Visibility===
			If the fur is thicker than this setting, then the underlying skin will not use physically based shading (note: this setting will be removed in a later version, and will be calculated automatically instead).

			===Normal Map===
			A normal map allows the skin to have fine 3D details, such as wrinkles, that will react to light correctly.

			[[File:Specular.jpg\|thumb\|An example of specular highlights (ie. the bright spots) reflecting off of my nose.]]
			===Specular Highlights===
			If enabled, specular highlights will show light sources being reflected off of glossy surfaces. The smoothness strength will determine how spread out or sharply focussed the reflection will appear.

			=== Two-Sided Rendering ===
			Normally, only the forward-facing side of the skin is rendered. If two-sided rendering is enabled, the back-facing side will also be rendered. An optional albedo colour, or an emission colour can also be applied.

			Note that the lighting calculations are always done from the perspective of the forward-facing side, which means that the lighting will be backwards for back-facing triangles.

			There is a slight performance hit of about 1-2% when two-sided rendering is enabled.
