Альфа в Unreal Engine 5 — research+setup, install gated на Epic account
TASK-037 partial. Research нашёл NanoGS plugin (Tim Chen, March 2026, UE5.6+, Apache-style, free) — perfect fit для canonical .ply Альфы. Plugin cloned + verified compatibility (tile_slicer.py читает alpha_canonical.ply без ошибок: 73,658 splats, корректный bbox). Final blocker: UE5 Linux binary download требует Epic Games account login (HTTP gate, не automatable). Full UE5 install + render demo — dedicated session work.
