* Added mix-and-match example to demonstrate the new Skin API. * Added mix-and-match example to demonstrate the new Skin API.
* Materials on `SkeletonRendererComponent` are now blueprint read and writeable. This allows setting dynamic material instances at runtime. * Materials on `SkeletonRendererComponent` are now blueprint read and writeable. This allows setting dynamic material instances at runtime.
* Added `InitialSkin` property to `USpineWidget`. This allows previewing different skins in the UMG Designer. Initial skins can still be overridden via blueprint events such as `On Initialized`. * Added `InitialSkin` property to `USpineWidget`. This allows previewing different skins in the UMG Designer. Initial skins can still be overridden via blueprint events such as `On Initialized`.
* `USpineWidget` will now report its own desired size based on the setup pose dimensions of the skeleton. This is used when selecting `Size to content` on a `USpineWidget` in the designer.
