Loads packs one by one so that duplicate file resolution
follows a deterministic order (last pack wins). Parallel loading made
the effective order depend on lock acquisition order, allowing older
packs to override newer ones. Sequential load stays under ~1s (~350ms
on typical hardware), so the performance tradeoff is considered acceptable.
- Guard leaf LOD access in CSpeedTreeWrapper::RenderLeaves() to avoid out-of-bounds indexing of m_pLeafVertexBuffer and m_pLeavesUpdatedByCpu.
- Skip leaf update/draw when LOD is invalid, inactive, empty, or has no vertex buffer.
- Add early safety returns for missing leaf buffer arrays and zero LOD count.
- Guard CSpeedTreeWrapper::EndLeafForTreeType() against null m_pLeavesUpdatedByCpu.
- Add shader re-init path in wrapper render entrypoints via CSpeedTreeForestDirectX8::EnsureVertexShaders() when cached shader state is missing.
- Introduce public EnsureVertexShaders() in SpeedTreeForestDirectX8 while keeping InitVertexShaders() private (resolves private-access compile error).
- Fix leaf shader input declaration to emit dcl_texcoord2 v9 for both GPU wind and GPU leaf placement configurations.
- Make LoadLeafShader() atomic: create new shader/decl first, then swap only if both succeed, preserving previous valid shader state on failure.
- Improve leaf shader failure logs to include HRESULT for easier diagnosis.
