…ets moved to VS as a result). compress instances to 64b, and sort by depth
Brings the grass rendering optimizations into the MT branch: - DX10/11 hardware instancing for details (single-copy VB/IB + per-instance vertex stream, 64B packed records, one DrawIndexedInstanced per detail object) - fill-once-per-frame instance buffer reused by sun cascade / spot light shadow phases (no refill, alpha smoothing once per frame) - distance fade moved to the vertex shader (dt_fade_params) - draws grouped by ShaderElement, front-to-back slot sorting - distance-based density falloff (r__detail_density_knee/_curve) MT-side adaptations made during conflict resolution: - instance records read mRotY_calculated (scale pre-multiplied in UpdateVisibleM on the MT worker) instead of the removed scale_calculated member - hw_Render/hw_Render_dump keep the light* L parameter; sector visibility culls (GMBase / L->GMLight vs pOutdoorSector) hoisted to per-dump early-outs since they are instance-independent; still details (var 0) keep skipping SMAP phases - upstream per-instance light-range cull dropped: out-of-range blades collapse to degenerate tris in the VS light fade instead - density falloff coexists with the upstream SSA-fade blade discard - fixed a missing-brace bug in hw_Render_dump's empty-variant early-out (the committed grass branch tip did not compile; fix was only in a stash) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

corrected shaders: I missed a typo Claude inserted when I was doing the dx10 stuff 🤦♂️ |
