An editor-only Unreal Engine plugin that streamlines asset interchange between Unreal Engine

and Poly Hammer's DCC tools.

Features:

- Groom export — Writes Groom Assets to an Alembic (`.abc`) file.

- Python API — The plugin's Unreal code is exposed to Unreal Python, alongside a`ph_interchange` package that wraps it for pipeline use.

- RPC server — For cross-application communication and end-to-end automation, with integrations for Unreal, Blender and other apps.

- MetaHuman character export — An Export Character For DCC asset action on a MetaHuman Blueprint writes a complete DCC package: head and body `.dna`, grooms, clothing, textures and a manifest, laid out the same way MetaHuman Creator's own DCC export is.
