全部 release
  1. v0.5.4.2Security Update: Compromised eMudhra CAs Refused最新正式版2026-11-01 · 2026-11-01 09:16 UTC

    LichtFeld Studio 0.5.4.2 is a security update. Please update.

    The private keys of eight eMudhra intermediate certificate authorities can be recovered from their certificates (disclosed on 2026-10-20). Anyone can therefore forge certificates that chain to these CAs. OpenSSL, which LichtFeld Studio and its Python runtime use, does not apply the operating system's distrust of them, and the previously bundled uv trusted them through its built-in roots. On an intercepted connection, a forged certificate could pass as a download or package server, and an intercepted plugin install could run arbitrary code.

    Highlights

    • Compromised eMudhra CAs refused. LichtFeld Studio's own downloads and plugin installs now reject certificate chains through the eight compromised CAs, checked against their public keys as Go and Node do, while every other chain is unaffected. The bundled uv moves to 0.13.5, which rejects them as well.
    • Security updates of dependencies. OpenSSL 3.6.5, curl 8.23.0, FFmpeg 8.1.2, libarchive 3.8.9, libpng 1.6.59, libtiff 4.7.2, libjpeg-turbo 3.1.4.1, FreeType 2.14.3, expat 2.9.0 and assimp 6.0.5.
    • POPSpa sparsification. Optional post-training sparsification removes splats the result does not need.
    • Training region of interest from the command line. --cropbox x0,y0,z0,x1,y1,z1 trains with the same crop box the GUI offers; --cropbox-loss-weight 0 ignores every pixel whose ray misses it. The box is saved with the project.
    • MRNF at the splat cap. Error-guided growth keeps exchanging splats once the cap is reached; its setting sits with the refinement parameters.
    • Interface. Selection outlines for splat objects, vertical category tabs in the right sidebar, a double-click on a setting's label restores its default, configurable arrow-key repeat for browsing camera images, a prompt to enable undistortion or GUT when distorted cameras are detected, comparison of splats and raw PLY point clouds in scene order, and the brand logo opens the Help menu.
    • Projects and plugins. An untrained project trains from the file alone, plugins can show scene nodes that are never saved, and GPU plugins default to no hot reload.
    • Fixes. Reopening a project with a training checkpoint keeps the viewer out of its degraded mode, the histogram no longer reads the live scene, a shared-memory race in the layer norm kernel, video frame extraction when the container outlasts the video stream, scaled training intervals that rounded to zero steps, enum property defaults, and Windows builds and DLL exports.

    What's Changed

    • Set the version back to 0.5.5 after the 0.5.4.1 release by @MrNeRF in #3695
    • Replace the Help menu label with a clickable brand logo by @jacobvanbeets in #3698
    • Let the layout test reach scrub fields through their drag handles by @MrNeRF in #3697
    • Keep MRNF's error-guided growth working at the splat cap by @hellguz in #3168

    • Compare splats and raw PLY point clouds in scene order by @shadygm in #3681
    • Clean up camera key repeat and point selection styling by @MrNeRF in #3706

    SAM 2.1 Hiera base+ weights with the video components (image encoder, prompt and mask decoders, temporal memory and object pointers) in the native .lfw format, used by native video masking. Marked as pre-release only to keep it out of the Latest badge; this is a permanent model asset, not an app release.

    • Source: official SAM 2 checkpoint sam2.1_hiera_base_plus.pt (sha256 a2345aede8715ab1d5d31b4a509fb160c5a4af1970f199d9054ccfb746c004c5), Apache-2.0, (c) Meta.

  3. v0.5.4.1Splat Drag Export, Batch Video Extraction and Crop-Box Training2026-10-18 · 2026-10-18 20:01 UTC
    查看更新说明

    Highlights

    • Drag splats out of LichtFeld Studio. Drag a model from the Scene Graph into a folder or straight into Blender as PLY or SPZ. Pick the up axis in Preferences; drops into Blender use its +Z up automatically on Windows and Linux X11. A paused training model gets its step in the file name.
    • Crop and transform with numbers. The crop box and ellipsoid have numeric position, rotation and scale fields, and every number field can be dragged left or right to change its value. Training can follow the crop box live without floaters, and you choose how much growth goes inside it.
    • Resume training. Stored training sessions can be resumed, including ones saved during sparsification, and the panels and status bar show paused and stopped runs correctly.
    • Video frame extraction. Batch extraction, exact FPS that follows the source frame rate, naming presets, configurable frame numbering, full-range colors and a software fallback for formats the GPU decoder cannot handle.
    • Viewing. Home View with Set Home and Reset Home, project-scoped Z-up navigation, point clouds and meshes in the panorama view, HDRI backgrounds in split views, meshes in depth views and the flat Graphite theme.
    • Evaluation. A compare command scores image sets, and masks select the same pixels in training, evaluation and SSIM.
    • Fixes. Image loading without a GPU JPEG decoder, Python console hangs, large group merges running out of VRAM, RAD LOD files in 3DGUT, keyboard layouts under X11, and Windows paths and builds.

    The modular workstation for 3D Gaussian Splatting

    Train, inspect, edit, automate, and export 3D Gaussian Splatting scenes from a single native application.

    LichtFeld Studio lets you train new scenes from COLMAP datasets, resume checkpoints, inspect reconstructions in real time, edit gaussian selections, extend the app with Python plugins, and automate workflows through MCP and embedded Python.

    Why LichtFeld Studio

    LichtFeld Studio is built for users who need more than a training script or a standalone viewer. It combines model training, real-time visualization, gaussian editing, export, plugins, and automation in one toolchain.

    • Train new 3D Gaussian Splatting scenes and continue experiments from checkpoints
    • Inspect reconstructions interactively while training or after convergence
    • Select, transform, and edit gaussian subsets and scene nodes with undo/redo support
    • Export results to PLY, SOG, SPZ, or a standalone HTML viewer
    • Extend the application with Python plugins and plugin-local dependencies
    • Automate workflows through MCP resources, MCP tools, and embedded Python

    Who It Is For

    • Researchers: iterate on reconstruction quality, inspect training progress, test advanced features, and export results for analysis or sharing
    • Production teams: inspect scenes visually, edit gaussian selections, and deliver portable exports without stitching together separate tools
    • Tool builders: integrate LichtFeld Studio into larger pipelines through plugins, embedded Python, and MCP-driven automation

    Capabilities

    • Training and iteration: load datasets, resume checkpoints, monitor progress, and evaluate changes in a desktop app or headless workflow
    • Interactive scene work: inspect reconstructions in real time, work with gaussian selections, and apply scene transforms with history support
    • Export and delivery: export results to common research and delivery formats, including a standalone HTML viewer for easy sharing
    • Extensibility: use the Python plugin system for custom panels, operators, tools, and dependencies
    • Automation surface: integrate LichtFeld Studio with local tools, scripts, and agents through MCP resources and tools
    • Research-ready features: MCMC optimization, bilateral grid appearance modeling, 3DGUT support for distorted camera models, and timelapse generation
    • Native performance: modern C++23 and CUDA 12.8+ for responsive training and visualization on NVIDIA hardware

    Optional POPSpa sparsification

    In the Training panel, enable Sparsity and set Target Gaussians under Sparsity Settings. The CLI equivalent is:

    --enable-sparsity --popspa-target-count 256000

    POPSpa runs after regular training: contribution scoring, an intermediate prune, sparse optimization, an exact final prune, and recovery. It supports FastGS and the bundled gsplat/GUT backend. The target must fit the active model count and retain all frozen Gaussians. Phase lengths and advanced controls are available as popspa_* settings in the UI, JSON, and Python. The equations follow KissGsVanilla (Apache-2.0), implemented independently in LichtFeld Studio's C++/CUDA.

    Support Development

    LichtFeld Studio is free and open source. If it is useful in your research, production, or learning workflow, please consider supporting its continued development.
