The GPU ECS Animation baker allows you to convert you existing animators & skinned mesh renderers to GPU ECS animators. 

The animators are convertable to ECS entities and the animations run entirely on the GPU.

This allows you to add crowds of animated characters to your Unity game. You can build realtime strategy games with large armies of individually animated characters, while preserving a decent framerate.
