…te-mode, Windows fixes Rendering features behind the shooter's visual pass: - Sky: analytic drifting cloud layer in the procedural-sky shader (env.rs); time fed via the unused SkyUniforms.intensity.y. - Fog: manual height-fog march now runs additively with procedural sky (post.rs) instead of only as the aerial-LUT else-branch, so haze works at sub-km scene scale. - Foliage: wind sway + backlit translucency for alpha-cutout materials in the scene shader (core.rs); wind appended to LightingUniforms (types.rs) with widened UBO visibility (lighting.rs, mod.rs). - Shadows: shadow pass renders immediate-mode + cached-model draws, not just scene nodes (shadow_pass.rs), so immediate-mode games cast shadows. - Device: raise max_sampled_textures/samplers per stage to the adapter max so refractive materials (19 sampled textures) compile (windows). - FFI: bloom_set_bloom_intensity/tonemap/auto_exposure_*, mesh scratch-buffer upload (createMesh i64 ABI fix), drawModelRotated re-export (visual.rs, models.rs, src/*). - Windows build: jolt default features, panic=abort, Jolt libDirs, LTCG off for lld-link (build.rs, Cargo.toml, package.json).

Trees/grass/leaves cast opaque rest-pose blobs because the shadow pass is depth-only. Added a SECOND shadow pipeline (pipeline_cutout, SHADOW_SHADER_CUTOUT) that samples the caster's base-colour alpha and discards below the material cutoff, so cutout cards drop their real (dappled) shape. The opaque shadow pipeline is byte-identical/untouched — only cutout cached models use the new path. GpuMesh gains a per-mesh cutout shadow bind group (base colour + sampler + cutoff), built in cache_model_if_static for alpha_cutoff>0; shadow_pass.rs selects the pipeline per caster and binds group 1 for cutout entries.
The planar reflection probe only rendered material-system draws, so immediate-mode games (which draw the world via drawModel) got a black/empty probe. Added a single-target reflection pipeline (REFLECT_SCENE_WGSL: base-colour x sun N.L + ambient, alpha-cutout discard) that renders every cached model (trees, house, foliage) into the probe with a mirrored, oblique-clipped VP. Owned bind-group layouts (dynamic per-draw model uniform + sun/ambient); reuses scene_material_bg for base colour. Probe clears to transparent so geometry writes alpha 1 and the water shader blends the probe over its analytic sky dome by alpha. Lazily built on first dispatch; no change to the opaque/main pass.
The planar-reflection scene shader negated the sun dir for N.L, which only matched when the caller passed a below-horizon (travel-direction) sun. Engine convention is direction-TO-sun everywhere (scene diffuse, shadow fit, sky LUT mu_s=sun.y), so use +sun_dir.

Rendering features added while building the Bloom Shooter's visual pass on Windows.
Sky
env.rs). Per-pixel view ray projected onto a virtual cloud plane (perspective convergence at the horizon), value-noise fBm coverage, faded near horizon + thinned around the sun. Time is fed through the previously-unusedSkyUniforms.intensity.y(no struct-layout change) so the clouds drift.Fog
post.rs) instead of only as theelseof the aerial-perspective branch. The procedural aerial LUT is km-scaled and negligible over a small (tens-of-metres) scene, so this restores controllable haze at scene scale. Guarded to skip sky pixels.Foliage
core.rs), gated on the cutout flag so opaque geometry is untouched.wind: vec4appended toLightingUniforms(types.rs); UBO visibility widened to VERTEX_FRAGMENT (lighting.rs,mod.rs).Shadows
shadow_pass.rs). Immediate-mode games (drawCube/drawModel) created no scene nodes and so cast no shadows before.Materials / device
max_sampled_textures_per_shader_stage+max_samplers_per_shader_stageto the adapter maximum (windows device request). The refractive material profile binds 19 sampled textures in the fragment stage; the default limit of 16 made it fail to compile.FFI
bloom_set_bloom_intensity/tonemap/auto_exposure_key/auto_exposure_rate; mesh scratch-buffer upload path (works around the createMesh i64 ABI break on Perry 0.5.1171);drawModelRotatedre-export from the main index (visual.rs,models.rs,src/*).Windows build
panic = abort, JoltlibDirs, and LTCG off so lld-link can read the Jolt objects (build.rs,Cargo.toml,package.json).Paired with Bloom-Engine/shooter PR (the visual overhaul that consumes these).
