Hydra is a rendering architecture part of USD, designed to abstract the host application from the renderer. A renderer implementing a Hydra render delegate can run in any host application supporting Hydra, which now includes Blender. For external renderers this means less code to be written, and improved performance due to a using a C++ API instead of a Python API. Add-ons need to subclass bpy.types.HydraRenderEngine. See the example in the Python API docs for details. An add-on for Hydra Storm will be included as well. This is USD's rasterizing renderer, used in other applications like usdview. For users it can provide a preview of USD file export, and for developers it serves a reference. There are still limitations and missing features, especially around materials. The remaining to do items are tracked in #110765. This feature was contributed by AMD.
