Fixed

  • [Voxel Shapes] Fixes a crash occurring when computing connected regions while resizing the memory area backing voxel shapes
  • [Voxel Shapes] Voxelization for connected region chunks is now prioritized to avoid "plopping" (the base chunk could disappear before the sub-chunks got spawned)
  • [Voxel Shapes] Fixes a rare issue where voxel shapes apply their previous linear and angular velocities after spawning
  • [Physics] Relaxed voxel shapes when penetrating each other

[0.1.1] - 2023.04.11
