Frame Studio - Gaussian splats (PLY, SPZ v2-v4), PLY vertex colours, panorama skies - Copy, cut, paste and duplicate for objects, splats and world items - Walkable-area rebake moved off the UI thread; viewport one frame sooner; refresh-locked pacing (FS_PACE=timer for the old one) - Fixed: bundle thumbnail use-after-free crash, auto-save deleting environments, saves into scratch copies, edits lost on non-ASCII paths, unopenable manifests with inf/nan, bundle save data loss, opening a home marking it changed, gizmo NaN, long paths, many malformed-file crashes - Updater verifies sha256, journals the swap and never leaves the exe missing Frame Home - Seats turn you to face their way - Draw batching (Hand Tutorials up to ~20% less GPU time), cut-out EQUAL pass, late head-pose read before submit - Proper queue-family hand-over to the compositor layer; layer descriptor generations and seqlocked slots; structural SPIR-V check - Fixed: hangs/crashes on damaged .fenv files and shaders, render-pass validation error, sync hazard in the foveation smoothing pass, unverified update downloads, half-done installs Tests: tests_loco/env_share/spv_check wired into CMake (FRAME_TESTS) and CI.
