Erik 9d4967a461 fix(core): ACME cross-check fixes — normals, placement, scenery 
Four fixes from the ACME StaticObjectManager cross-reference:

1. GfxObjMesh: normalize vertex normals (1d). Dat normals may not be
   unit-length; without normalization, lighting is wrong per-vertex.

2. SetupMesh: add third-fallback placement frame (2a). If neither
   Resting nor Default exists, use the first available frame from
   PlacementFrames. Matches ACME's GetDefaultPlacementFrame.

3. SceneryGenerator: building cell exclusion (4d). Compute which
   terrain vertices have buildings (from LandBlockInfo.Objects +
   Buildings), skip scenery spawns in those cells. Prevents trees
   from spawning inside building footprints.

4. SceneryGenerator: slope filter (4e). Compute terrain normal Z at
   each displaced position and check against ObjectDesc.MinSlope /
   MaxSlope bounds. Prevents trees from spawning on cliff faces.

Also confirmed 4f (scenery Z=0) is NOT a bug — GameWindow's hydrator
lifts scenery to terrain Z at line 1213. The Z=0 in SceneryGenerator
is a placeholder correctly overridden at render time.

acdream

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.
