Hotfix: • Fixed MCMC training collapse on outdoor sets — Gaussian count no longer drops to 5 mid-training, no more GPU watchdog kills on large reconstructions. • Browse Files now correctly loads photos from folders containing subfolders. • COLMAP import keeps you on the import view so you can adjust settings before training. Thanks to community testers for the detailed bug reports.

Stability improvements: • Fixed crashes that could occur in the 3D viewport during training on some Macs. • The viewport now uses a simpler, more robust rendering path on macOS — this also removes occasional tile-block artifacts. • Prevented a rare situation where the app could become unresponsive while rendering a frame.

v1.4.2 — COLMAP import, Sky Dome, demos, storage manager and rendering fixes NEW: • Try Sample Scene: load a pre-trained orchid splat (~6 MB) instantly — see a finished result without running training. • Download Sample Photos: 960 demo frames (~58 MB) fetched from GitHub — runs the full SfM + training pipeline end-to-end. • New COLMAP drop zone: drop existing photogrammetry workspaces directly — a decision dialog lets you pick "use existing reconstruction" or "re-run". • Sky Dome V2 (optional, off by default): projects sky pixels onto a sphere around the scene before training → fewer outdoor floaters. • Manage Storage (Help menu): review every RadianceKit asset on disk — logs, exports, scenes, captures, imports — with reveal-in-Finder and delete actions. • Continue Training: extend a finished run by +5K, +10K, or +20K iterations using the saved engine state. • SfM Export to transforms.json (File → Export → Photogrammetry): take scenes into nerfstudio / Brush without re-running COLMAP. • Acknowledgements section in the in-app User Guide (English + German). IMPROVED: • Throttle slider moved from Expert Mode into Settings → Training (Off / 2 ms / 5 ms / 10 ms picker). • Quality preset reduced from 40K to 35K iterations — Truck benchmarks showed over-training in the last 50%. • 8 GB Memory Guard: low-RAM Macs auto-pick Quick preset, cap image resolution at 1536 px, use a smaller buffer pool. • Tile artefacts fixed: removed black 16×16 blocks in dense cluster regions. • Stabler GPU forward-pass bindings, no more latent memory-corruption path. • Drop accepts files anywhere in the window, layouts wrap cleanly. FIXED: • Trial expired bug on a second Mac: silent Keychain failure no longer locks honest users out. • Continue Training cancel: state returns to "completed" so a new continuation runs immediately. • Loss chart continuity: continuation logs L1 (matching the initial run) instead of L1+SSIM. REMOVED: • Low-Texture Masking toggle (Experimental → Outdoor Floater Reduction): drone A/B showed it ate legitimate scene content. Minimum requirement: macOS 26.0 Tahoe.

• Sky masking: automatically detects and masks sky regions to reduce floaters in outdoor scenes • Low-texture masking: reduces artifacts on plain walls, floors, and other textureless surfaces • Improved video import progress display • New App Store screenshots and preview video

Drastically reduced memory usage for large datasets (500+ images). Image loading pool now capped at 64 images instead of growing unbounded.

Fixed: Language menu now works and switches the interface instantly. Added "(Language)" hint to all non-English language labels for easier navigation.

New in v1.3.0: - Live Preview: Watch the 3D scene build up in real-time during training - Folder Import: Drag entire image folders directly into the app - QuickLook: Preview imported images with the spacebar - Keyboard Shortcuts as a standalone window - Improved localization across 17 languages - Brush Editor: More precise selection at viewport edges - Colored transport controls (Play/Pause/Stop) - About window with developer info

Bug fix: Video import now works correctly with Structure from Motion.

What's New in v1.2.0: • Fixed file access for external drives, iCloud and Desktop folders • Reduced memory usage for high-resolution images (4K+ now works on 16 GB machines) • Added TIFF format support • Lowered minimum macOS requirement to 26.0 • Added 16-bit image detection with info logging • Export files now include "Made with RadianceKit on Mac" metadata Improvements thanks to the fine people of r/GaussianSplatting on Reddit — your feedback makes RadianceKit better!

New trial experience with 3-day free trial. After expiration, export, expert mode, and premium quality presets require the full version.

- User Guide: More reliable rendering (replaced WKWebView with native SwiftUI) - Light and Dark Mode support in User Guide - Keyboard Shortcuts menu disabled when no viewport is active
