+AnimationMatchModifierAsset
+===========================
+
+This is a SkeletonDataModifierAsset. Add it to a SkeletonDataAsset to apply its effects when its SkeletonData is loaded.
+
+AnimationMatchModifierAsset processes animations so that their timelines match. This allows them to function with naive Animation Apply systems such as SkeletonMecanim without the need for autoreset functionality.

+SkeletonRendererCustomMaterials by LostPolygon
+===============================
+This is a basic serialization and inspector implementation for custom material overrides for SkeletonRenderer and its derived classes (SkeletonAnimation, SkeletonAnimator).
+
+## How to use
+Right-click on your SkeletonRenderer and select "Add Basic Serialized Custom Materials". This will add and initialize the SkeletonRendererCustomMaterials to the same object.
+
+You can use this to store material override settings for SkeletonRenderer instances/prefabs so they will be applied automatically when your scene starts or when the prefab is instantiated.
+
+This script is not intended for use with code.
+To dynamically set materials for your SkeletonRenderer through code, you can directly access `SkeletonRenderer.CustomMaterialOverride` for material array overrides and `SkeletonRenderer.CustomSlotMaterials` for slot material overrides.

+# Unity Sprite Shaders
+An Uber Shader specialised for rendering Sprites in Unity.
+Even though it's designed for Sprites it can be used for a whole range of uses. It supports a wide range of optional shader features that won't effect performance unless they are used.
+It also supports per-pixel effects such as normal maps and diffuse ramping whilst using Vertex Lit rendering.
+
+### Lighting
+The shaders support lighting using both Forward Rendering and Vertex Lit Rendering.
+Forward rendering is more accurate but is slower and crucially means the sprite has to write to depth using alpha clipping to avoid overdraw.
+Vertex lit means all lighting can be done in one pass meaning full alpha can be used.
+
+### Normal Mapping
+Normals maps are supported in both lighting modes (in Vertex Lit rendering data for normal mapping is packed into texture channels and then processed per pixel).
+
+### Blend Modes
+Easily switch between blend modes including pre-multiplied alpha, additive, multiply etc.
+
+### Rim Lighting
+Camera-space rim lighting is supported in both lighting modes.
+
+### Diffuse Ramp
+A ramp texture is optionally supported for toon shading effects.
+
+### Shadows
+Shadows are supported using alpha clipping.
+
+### Gradient based Ambient lighting
+Both lighting modes support using a gradient for ambient light. In Vertex Lit mode the Spherical Harmonics is approximated from the ground, equator and sky colors.
+
+### Emission Map
+An optional emission map is supported.
+
+### Camera Space Normals
+As sprites are 2d their normals will always be constant. The shaders allow you to define a fixed normal in camera space rather than pass through mesh normals.
+This not only saves vertex throughput but means lighting looks less 'flat' for rendering sprites with a perspective camera.
+
+### Color Adjustment
+The shaders allow optional adjustment of hue / saturation and brightness as well as applying a solid color overlay effect for flashing a sprite to a solid color (eg. for damage effects).
+
+### Fog
+Fog is optionally supported
+
+
+## To Use
+On your object's material click the drop down for shader and select Spine\Sprite\Pixel Lit, Vertex Lit or Unlit.
