This is an example implementation of model animation in MonoGame using a skinned effect shader.
Build the pipeline extension first. This creates the library used by the content builder to import and process the skinned model and its animation clips (from model.json).
During content build, the AnmatedModelImporter in AnimatedModelPipelineExtension imports the FBX model and animation clip information from the json content.
AnimatedModelProcessor processes the model using the fbx processor and also extracts the bone data, using an implementation based on the Microsoft XNA example.
The AnimatedModel class wraps the model with its animation data, and is loaded into the example project using the content builder as usual.
When the animation is played, bone data is updated via the AnimationPlayer, and sent to the AnimatedModelEffect which is used to draw the model.
The HLSL source code for the shader is inclued in AnimatedModelLib/Effects/Source.
Since this processor does not support multiple animation clips in the FBX format, the animations are baked into the fbx as one long animation.
The animation clips represent slices of the timeline used for playing each animation.
When playing the example animation, use 'Space' to cycle through the animation clips.
The rigged models and animations were sourced from Kenney's Animated Characters 1 under CC0 1.0 Universal license.
