Engine v4.3.1

May 13, 2026

A patch in the Groovy line.

what's new

Walls and floors are back in 3D Rooms games. Players land cleanly, walls stop the player, and skeletons stand on the floor instead of falling into it.

›technical notes

Fixed 3d-rooms terrain colliders silently dropping out of Rapier (#6483). resolveColliderMesh + isMeshColliderReady in apps/cf-kernel/src/engine/physics/rapier/bodies.ts gated bespokeMesh readiness on top-level mesh.indices.length > 0, but buildRoomsBodyConfig packs each rooms floor/wall/ceiling box into hulls[] as a convexHull point cloud with empty top-level indices. Readiness check now accepts hulls-only meshes; per-hull threshold matches the convexHull creation path at bodies.ts:1057. Introduced in #6417, surfaced 7 days later from a 3d-rooms game report.
