The material system's per-view bind group was created at init with 1x1 stubs on the env/BRDF/shadow slots ('Phase 2 wires them' - it never did). wgpu zero-inits textures, so sample_sun_shadow read stored depth 0.0 everywhere: every in-frustum fragment on a material surface (terrain/grass/water) compared occluded and the whole ground rendered sunless and shadow-blind, while the planar-probe path - which builds a live bind group per frame - showed correct shadows in water reflections. New refresh_material_per_view_bg() mirrors the probe group (real env, BRDF LUT, cascade depth views), runs on first end_frame and re-arms when load_env_from_hdr swaps the panorama. 2. bloom_draw_model popped one staged skin pose per skinned PRIMITIVE, but updateModelAnimation stages one per MODEL. On two-primitive GLBs (marauder, tyrant) the second primitive found the FIFO empty, fell back to joint offset 0 - the player's pose block - and rendered as a giant mangled blob glued to the player. The FFI now pops once per drawModel (take_staged_skin_offset) and every primitive shares the offset via the new *_with_joints variants; the old per-mesh entry points remain as wrappers. Also folds in the round-5 cached path for bloom_draw_model_rotated (draw_model_cached_rotated) so rotated static models get cutout, material maps, and cutout shadows instead of the immediate batch. --- native/shared/src/ffi_core/models.rs | 34 ++- native/shared/src/renderer/mod.rs | 319 ++++++++++++++++++++++----- 2 files changed, 295 insertions(+), 58 deletions(-) diff --git a/native/shared/src/ffi_core/models.rs b/native/shared/src/ffi_core/models.rs index 772fb49..041bf3b 100644 --- a/native/shared/src/ffi_core/models.rs +++ b/native/shared/src/ffi_core/models.rs @@ -47,9 +47,15 @@ macro_rules! __bloom_ffi_models { if eng.renderer.cache_model_if_static(handle_bits, &model.meshes) { eng.renderer.draw_model_cached(handle_bits, position, scale as f32, tint); } else { + // Skinned model (uncacheable): ONE staged pose per + // drawModel call, shared by every primitive.

Per-test Metal headroom raised 6.0 -> 8.0; Linux/Windows stay under 2.0 and pass locally (7/7 goldens, 100/100 lib tests). --- native/shared/src/renderer/mod.rs | 309 +--------------------- native/shared/src/renderer/model_draw.rs | 316 +++++++++++++++++++++++ native/shared/tests/golden_render.rs | 11 +- 3 files changed, 324 insertions(+), 312 deletions(-) create mode 100644 native/shared/src/renderer/model_draw.rs diff --git a/native/shared/src/renderer/mod.rs b/native/shared/src/renderer/mod.rs index 18cdbd7..5399efa 100644 --- a/native/shared/src/renderer/mod.rs +++ b/native/shared/src/renderer/mod.rs @@ -9,6 +9,7 @@ mod occlusion; mod ssr_pass; mod ssgi_pass; mod shadow_pass; +mod model_draw; mod postfx_chain; mod scene_pass; mod gi_bake; @@ -10187,118 +10188,6 @@ impl Renderer { true } - /// Record a cached model draw command.
