The retrace after the label-swap fix showed getParameters unchanged (~2.5s / ~4% throttled main thread) — the real driver is Three r158+'s transparent-DoubleSide two-pass path: renderBufferDirect renders such objects back side then front side, setting material.needsUpdate BOTH times, i.e. a full getParameters/program-cache lookup twice per object per frame, plus double draw calls. (Found by reading the two-pass branch in the vendored three.module.min.js right next to the getParameters call site.) All 18 transparent DoubleSide materials in this renderer are flat unlit quads — technique markers, sustain rails, chord frames, lane planes, halo bars — where the two-pass self-occlusion ordering buys nothing. Declare forceSinglePass: true on all of them. Also corrects the _setLabelMap comment's churn attribution (that fix removes the label-swap contribution; this one removes the dominant source). Plugin 3.31.1 -> 3.31.2. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |
