67js 0.18.0

• Clip layers on an imported asset take a strip with start, scale, repeat, blend in and out, extend and blend mode, so a walk repeated three times can crossfade into an idle (#693)
• Particle emitters take points from a mesh surface (weighted by area), its vertices or its closed volume, push them along the normal, and draw each particle as one of up to 8 listed nodes with a random or surface-aligned rotation (#695)
• scene_apply takes bake-motion: it samples nodes over a range into keyframe tracks (tracks, IK, constraints, drivers, ragdoll and rigid bodies), optionally drops keys within a position and angle tolerance, and removes the sources it replaced, so the motion exports as a clip (#697)
• sdf geometry meshes a tree of sphere, box, round box, capsule, cylinder and torus shapes with union, subtract, intersect, smooth blends and offset by surface nets, so blobby bodies and rounded joins need no hand modeling (#700)
• curve geometry takes kind poly or nurbs, several splines, arc, spiral and star shapes and a trim, so rails, ropes and a growing vine need no hand-placed points (#701)
• uv_project (cube, cylinder, sphere) and uv_pack mesh edits write and pack UVs with one texel density (#702)
• mesh_edit gains poke, dual, tris_to_quads, symmetrize, scale_elements and extrude_edges (#703)
• Add a build mesh modifier that reveals faces over start and length frames in index, seeded random or axis order, with reverse (#704).
• scene_restore takes revision to undo the last few scene_apply edits in one call, with no checkpoint made first (#744)
• Docs: add an FAQ page for the questions from the launch: three.js, size and speed, tokens, what the agent sees, undo and diffs (#745).
• Set SIXTYSEVENJS_MCP_LOG=<file> to log each MCP tool call (tool, duration, ok, result size, never arguments), and run scripts/summarize-mcp-log.mjs for calls, error rate and median duration per tool (#746)
• Depth precision by default (#751, phase 1 of 2): the colour pass draws with reversed-Z and a 32-bit float depth buffer wherever EXT_clip_control exists, at any far / near ratio, from the first frame; the 16-bit depth buffer is gone; without the extension the depth buffer is 24-bit and the near plane fits the visible bounds when the camera left near unset; reversedDepth: false opts out; installDepthPrecision, hasFarOverlap and requestReversedDepth are removed (use installCoplanarDiagnostics for the warning); bench/flicker/index.html is a viewer with a flicker probe
• Flush faces stop flickering by default (#751, phase 2, step 1 of 2): faces that lie on one plane or a few millimetres apart, inside one mesh or across parts, are ranked per triangle and drawn with a small view-space depth bias, so the face in front wins at every distance and on every depth format; agent scenes do it unless environment.resolveCoplanar is false, a renderer does it with resolveCoplanar: resolveFlushParts; decal and depthLayer use the same bias; what cannot be ranked (more than 15 faces stacked on one plane, double-sided faces a gap apart) comes back as a coplanar-overlap warning with a reason; coplanarLayers, resolveCoplanarParts and EXACT_FLUSH_DISTANCE are removed; bench/flicker has trap scenes (?trap=, probe.mjs --traps)
• Hidden flush faces are cut away (#751, phase 2, step 2 of 2): where an opaque face covers another on exactly the same plane (1 cm2 or more), the covered part is cut out of the copy the hidden face draws with, every vertex array interpolated, so a stack of any depth on one plane stops flickering and no longer reports rank-overflow; parts and their geometry stay as they are (flushOrderOf(part).geometry holds the cut copy), instances of one geometry share a cut, and the path tracer traces the cut geometry; a face under a blended or masked face, or a double-sided face under a one-sided one, is still ranked; bench/flicker gains the plaque-closeup-0.5m trap with an open-pixel count
• Near-flush faces are cut too (#751): an opaque face in front of another by at most a thousandth of the side of their shared area (from 1 mm to 1 cm) cuts the face behind it, as a flush face does, instead of taking a rank; the Melbourne city model, whose stacked blocks nest facades 5 to 17 mm apart up to 17 deep, now reports no rank-overflow
• scene_inspect and scene_capabilities take the inputs Haiku sent in the bench: short mesh edit branch names (meshEdit.inset), dotted fields (environment.spotLights), near topic names (uvs, scene.terrain), source nodes without a mesh of their own, includeBounds with kind hierarchy; an unwalkable path start names the nearest walkable point (#761)
• scene_inspect with a node ID lists the parts below it and tags each with fromNode; a node with no part below it, such as a skeleton joint, returns its transform (parent, joint flag, local translation, rotation and scale, rest world position) instead of an error (#761)
• 67js/addons/runtime adds createRuntime, a live game loop with fixed, variable or interpolated steps, ordered pluggable systems, pause on a hidden tab and a frame-time readout (#770)
