Whats new in 2.11

Highlights
  UMA avatars are now visible at edit time, and can be modified directly in the editor.
  Significantly faster UMA builds in built applications
  More than 4 bone weights per vertex
  Better usage of texture atlas using new fit methods
  Transform (scale and rotate) overlays in recipes
  Backup/Restore of global library
  Numerous bug fixes

Generation
  Added support for more than 4 boneweights. Can now use as many boneweights as you like. 
  Reworked the SkinnedMeshCombiner to use the new boneweights.
  New "no coroutines" method of generation results in faster build
  Skeleton removal during build is now done in build process to fix issues where skeleton is not available during some frames.
  New texture atlas fitting methods:  
     Reduce (with a variable reduction amount)
     Best Fit Square (Expands the texture to the best fit square, and then reduces them to fit the atlas). This takes a bit more work, but wastes the least space.
  Broke out fit methods on generator
  Added property to sharpen reduced textures by forcing it to use a higher mip. Produces significantly more detailed output on textures that are fit.

Scenes
  Updated many scenes to use better lighting.
  Updated Mounting Objects example scene to show how to use UMAMountedItem.
  Updated Ragdoll scene to show how to detect what part of the body is hit.

Recipes
  Added ability to transform (scale and rotate) an overlay in a recipe (Not on first overlay - only additional overlays)
  Added ability to change color channel length on shared colors in recipe editor.
  Added Property Blocks to Overlay Colors (shared colors). Now you can set floats, vectors, ints, colors, matrixes, etc. on the materials.

ExpressionPlayer
  Added Pointing, Peace Sign, Rude sign, and grasp to Expression Player. Note: the arms/hands must be procedurally driven for this to look right (VR, etc).
  Fixed some errors where the Expression Player could generate errors during startup

DynamicCharacterAvatar
  UMA characters are now visible at edit time (can be disabled)
  Made an edit time DNA editor, combined with colors and wardrobe under "customization".
  Added filters to colors in DCA customizer section
  Added UpdateBounds() function.
  Added load/save preset in the editor.
  Default colors are now white/black for the various colors on the race.
  New events: WardrobeAdded and WardrobeRemoved. 
  Added "Always Rebuild Skeleton" option in the advanced settings. This will help you keep your rig clean and tidy, for a slight performance cost.

UMAMountedItem
  New object to make mounting simpler. Add this to an object you want to make mountable. Specify the bone you want to attach it to, and any offset/rotation. Will automatically attach and process, and survive rebuilds.

OverlayData
  Made it possible to have Overlays with no texture channels (these overlays can be modified with material property blocks).

SlotData
  New: Wildcard slots. This is a type of utility slots that can be added to recipes, which allows you to place overlays onto slots (or other overlays) based on tag. So you can place an 
       overlay onto a "Torso" without knowing the actual slot ID, just the tag. This allows you to reuse recipes for slots that have the same UV coordinates.
Slotbuilder
  Made blender slot rotation fixup optional.
  Can now specify bones to keep when building slots. (for mount points, etc)

Global Library
  Functions (and menu items) to backup and restore the Global Library.
  Made the Build Preprocessor optional (off by default)

Misc
  Set proportions on default female race to a bit less heroic.
  Fixed some possible warnings during overlay generation.
  Fixed race loading in editor so it does not need to instantiate the race to get slots
  Lot of minor issues where assumptions were made in code that occasionally weren't true.
  URP conversion option will convert hair to use Speedtree8 shader
  Forearm Twist slot script will now let you set the names of the bones
  Reworked the bone cleaner to make it more robust
  Added flipping, highlighting to bone pose editor
  Added "find UMA" to bone pose editor, so you don't have to select it
  Bone Pose Editor will now remember the selected UMA when possible
  Bone Pose Editor will now allow mirroring on X,Y,Z axis. Default UMA (blender export) is on Y axis.  
  Provided sane colors for additive channel when an overlay did not have all channel colors defined (issue with core samples)
  Tightened up avatars, and made the new avatars the default
  Numerous bug fixes on edge cases
  Better resource cleanup

DCARendererManager
  Added option EnableRenderers to turn on/off the renderer manager for toggling between first and third person.
  

What's new in 2.10.1

   Fix for MeshHideAsset editor scene in HDRP, 2019.3+





What's new in 2.10 

Minimum supported version is 2018.4
Requires .Net 4.X compatibility in player settings. 

Important: In this version, the DynamicAssetLoader is only kept for compatiblity with old projects. To use Asset Bundles, you should either use Addressables, or manually download them and load them into the library.

Support for Addressables
  Automated generation of addressables groups (including LOD slots)
  Automated labelling of indexed items by recipe (including LOD slots)
  Automated cleanup of slots/overlays/textures
  Significantly reduced memory overhead
  Build requests are queued up with all relevant data
  Added recipes to Addressables. If you do this, you must load them before access (they are all labelled by recipe and with 'UMA_Recipe')
  Will now Keep shared group on regeneration. 
  Can now filter on non-added recipes.
  Can now individually choose to add a recipe to addressables, or to update a recipe. 
  Plugin system to customize how addressables are generated.

New global library window
  New functions to mark items by various parameters
  New Addressables Menu to generate items
  New Ability to remove unused slots/overlays using the addressable groups (Remove Orphans). Requires generating labels from recipes.
  New Ability to remove items from library by dropping a folder onto the lib
  Repair function will now attempt to repair addressable item groups and labels
  Can view if an item is in resources, or addressable now
  Protected resource items from being deleted as orphans
Added a label field to recipes to allow the user to override addressable label names
Moved Mesh  Hide mask creation to mesh building, to address sync issues
Updated DNA checks to pull from global library instead of searching resources. Fixes an issue on android
When the animator is rebuilt, the layer weights are saved and restored now
LoadFromRecipeString now has a flag to clear the existing wardrobe when loading
Added SetRawColor function (and code) so you can pass in an OverlayColorData and the sytem won't monkey with it
UMAMaterial Changes
   Added checkbox to use the overlay multiplier color as the background for alpha blended overlays. 
   Added a multiplier to allow adjusting that color. This improves the look of hair (gets rid of banding on the edges)
   Added a "Non Shader Texture" flag to the texture channels. This allows a texture to be combined, but it will not be set on the material.
   Added menu option to convert all UMAMaterials to use LWRP/URP material property names. you will still need to run the unity update utility in addition to this.
Added Animation Clip Target Renamer to help with renaming targets for UMAs when the animation is broken
Reworked compatible races recipe loading, so they are figured out in the index at startup
Context changes
    Created a new UMAGlobalContext context that pulls everything from the global library. 
    (This removes the need for the various libraries - racelibrary, slotlibrary, etc.)
    All access to UMA data now goes through the contexts.
    Created new prefab UMA_GLIB using the global context. It is recommended to switch to this version in 2.10.
LOD Improvements
    Added "Maximum LOD Level" to SlotDataAsset, and Suppressed flag to SlotData for use by LOD systems
    Added "Use Slot Dropping" to UMASimpleLOD, this will suppress slots based on the fields above.
    By default, the eyebrows, eyelashes, and Inner Mouth are set to drop after LOD 0. Eyes are set to drop after LOD 1.
Ability to hide slots by Slot tag.
Added support for 32 bit index buffers (large meshes). To enable, add UMA_32BITBUFFERS to the player defines. This is experimental at this time.
Verify button in Slot Builder Window will detect UV Coordinates that are out of range.
Added Elf male and Elf female races with base race recipes.
CollisionMatrixFixer will read the current layermask settings for Ragdoll and NoCollisions, and use those if found.
Added "AutoSetLayers" property to UMAPhysicsAvatar. When set, the player layer will be the current gameobject layer, and the Ragdoll layer will be read from the layermask settings.
Added Shader Parameter Mapping to UMAMaterial - UMAMaterials can now map shared colors to color properties in the generated material. Useful for shaders that have extra color parms (like skin & hair shaders).
Added "AtlasResolutionScale" to DynamicCharacterAvatar. Using this, you can lower the atlas resolution for specific avatars, for example ones used for icons, etc. Warning: UMASimpleLOD can override this, so don't use in conjunction with that component.
Added "Resources Only" flag to UMA recipes. Checking this will skip adding this recipe, and it's slots, overlays and textures to Addressabe groups.
New Menuitem on UMA Menu: "WebGL/Enable Embedded Resources". This will turn on embedded resources in WebGL, allowing UMA to work right in WebGL.
Overlay coordinates can now be specified in UV range (0..1) in addition to absolute range. This should make it much easier to handle Unity converting textures to square on mobile, or the need to resize textures for performance.
New Detail Normal map texture channel type, allows combining of normal maps in UMAMaterials (standard renderer only at this point)
New Non-Shader texture channel type, allows a texture to be accumulated on the atlas, but not sent to a material. 
The first RuntimeAnimatorController for compatible races will now be added if a race specific controller is not found.
You can now pass a constructed DynamicCharacterAvatar to the UMARandomAvatar.Randomize() function to regenerate it randomly.
New scene ("OverlayAligner") to convert and adjust overlay coordinates visually. 
Performance improvements - up to a 5% increase in speed when building under 2019.3 due to boneweight optimizations.
Added support for more than 32 wardrobe slots (problem with Masked Field editor)
Added DefaultRendererAsset property to DynamicCharacterAvatar. This lets you set "UpdateWhenOffscreen", the renderer name, etc, for the default renderer. If you don't add a DCA Renderer Manager, or setup a Renderer Asset for a slot, this one will be used to set renderer properties.
Standard Races now use mecanim-friendly avatars by default

New "How To" scenes
 * How to construct a DCA from scratch
 * How to construct and load a DCA from a prefab
 * How to load and save a DCA to a string
 * How to use a slider to control DNA

    Sometimes a shader would not be compiled correctly.
    Reworked recipe editor and disallowed duplicate mesh hide assets.
    Fixed bug where you couldn't add a Wardrobe Collection using SetSlot before Start() was called on the DCA.
    Fixed bug in 2019.3 where it was not finding the type for RuntimeAnimatorController in build.
    Fixed bug where WardrobeCollections would end up indexed in multiple places
    If you supply an avatar and animator from the project, it will no longer attempt to delete the avatar when changing the race
