Erik 29fe0c0714 fix(app): terrain cull exempt + yaw preservation on Tab toggle 
1. Terrain culling: TerrainRenderer.Draw now accepts neverCullLandblockId,
   matching StaticMeshRenderer. Both renderers skip frustum-culling the
   player's current landblock. Previously only entities were exempt but
   the terrain under the player still disappeared when looking away.

2. Yaw drift on Tab toggle: render loop stores rotation as Yaw - PI/2
   (AC model facing offset), but yaw extraction on re-entering player
   mode didn't compensate. Each Tab cycle rotated the player 90 degrees.
   Now adds PI/2 back when extracting from the quaternion.

Experimental modern open-source Asheron's Call client in C# / .NET 10.

Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.

Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).

Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.

Layout

  • src/AcDream.Cli/ — console app that dumps asset counts from a dat directory
  • references/ — local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.

Run

dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"

Or set ACDREAM_DAT_DIR and run without args.
