Erik 6a55838a10 perf(rendering): true DrawElementsInstanced — one draw call per (GfxObj × sub-mesh) 
Replaces the per-entity glUniform uModel path with a shared instance VBO and
DrawElementsInstanced. All instance model matrices are uploaded to GPU once per
frame; the VAO's per-instance attribute pointers (locations 3–6, divisor=1) are
updated with a byte-offset re-point per group so a single VBO serves all groups
without requiring DrawElementsInstancedBaseInstance (not in Silk.NET 2.23).

Changes:
- InstancedMeshRenderer: add _instanceVbo, _instanceBuffer scratch; EnsureUploaded
  sets up mat4 instance attrs (locs 3–6) from the shared VBO; Draw builds the flat
  float[] of all instance matrices once then calls DrawElementsInstanced per sub-mesh.
  Drops the unused uint TerrainLayer attribute (loc 3 from vertex VBO) — mesh shaders
  never used it. Adds InstanceGroup helper to track per-group buffer offsets.
- mesh_instanced.frag: replace sampler2DArray+uTextureLayer with sampler2D uDiffuse,
  matching the existing TextureCache / individual-texture pipeline.
- mesh_instanced.vert+frag: track as committed files (were untracked).
- Shader.cs: add SetVec3 helper needed for uLightDirection uniform.
- GameWindow.cs: switch mesh shader load from mesh.vert/.frag to
  mesh_instanced.vert/.frag.

Visual output is identical: same entities, same textures, same lighting constants
(SUN_DIR=(0.5,0.4,0.6), AMBIENT=0.25, DIFFUSE=0.75 — moved from frag to vert).
Build: clean. Tests: 431/431 green.

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.
