BRILL REALM - WORLD MATERIALS 2026 - RC1.1 (HIGH FIVE / BARTZ)
===========================================================

This is an installation-ready test candidate, not a 4K remake of the
entire Lineage II engine.

CONTENTS:
- Reworked diffuse texture surfaces for selected towns, castles,
  surrounding terrain, foliage, NPCs, creatures, accessories and weapons.
- Version-matched binary difference patches in the deltas directory.
- SHA-256 source and output manifests, installer and backup restoration.
- No original game textures, models, game system/executables, or server
  configuration files are included in this ZIP.

INSTALLATION (Windows 10/11):
1. Make sure your full High Five client is already installed on disk.
2. EXIT Lineage II and your BRILL REALM launcher.
3. Unzip this archive to an ordinary directory.
4. Run INSTALL_BRILL_REALM_HD.cmd from that extracted directory.
   It starts a readable PowerShell script under your current Windows
   execution policy. Do NOT disable Windows Defender/security.
5. When prompted, choose the original client ROOT (contains system/L2.bin
   and both Textures and SysTextures folders).
6. Every source UTX must match a known approved SHA-256. The installer
   prepares and checks ALL patches before replacing ANY live game file.
   It refuses unknown/missing files. It creates verified backups in
   BRILL_REALM_Backups inside the game directory.
7. If successful, open the launcher and enter BRILL REALM / Bartz.
   Test Giran, Aden, Dion, Rune, Oren, Goddard, Schtgart and characters.
8. Restore via RESTORE_BRILL_REALM_HD.ps1 with the client and backup path
   if you need to undo the update.

LIMITATIONS:
- These textures are new 2026 material remaps, but retain the native
  High Five texture dimensions, renderer, UVs and existing models.
- Not all available zones, animated character models or water shaders
  are changed. Do not call it a full engine upgrade.
- Physical Windows client/gameplay/fps/teleport/relogin test remains
  unconfirmed. No runtime test on Windows PC was possible in build env.
- Some custom clients have other UTX versions and are intentionally
  blocked by installer until versions are reviewed.
- Do not replace system/L2.bin, run untrusted executables, or disable AV.

RELEASE NOTES:
See manifest.json for each file and SHA-256. This archive contains only
changed-block deltas and a reversible installer, not the game client.
