v2026.8.28

Changelog

• General training speed improvement
• Fixed training blackout with some GPU/driver combinations – please submit a new issue if you see blackout again
• Training quality improvement for sky and large low-texture surfaces
• Optimize system RAM usage for meshing
• Use separate regularization for surface cleanliness and overexposure
• SfM: Automatically retry with CPU fallback when GPU bundle adjustment gives error
• Fixed missing depth and normal maps when creating dataset from folder of images

Notes:

• This release carries difference in training quality intended to be improvement. Please submit an issue if you notice significant quality degradation compared to previous versions on your dataset.
• macOS binary is not included in this release since I've returned the Mac I borrowed for testing. If you are a Mac user, you may download binary from v2026.8.17 release, or build the latest code from source.

v2026.8.23

Changelog

• General improvement in splat quality
• Add options to delay distortion refinement and per-image intrinsics to improve SfM robustness
• Fixed a bug that causes noise and SH background to oversaturate
• Fixed "Unsupported camera model / distortion tier" error on some datasets
• Support initializing PPISP exposure from EXIF
• Slight training speed improvement on some datasets

Note:

• This release carries difference in training quality intended to be improvement. Please file an issue if you notice significant quality degradation compared to previous versions on your dataset.
• macOS binary is not included in this release since I've returned the Mac I borrowed for testing. If you are a Mac user, you may download binary from v2026.8.17 release, or build the latest code from source.

v2026.8.20

Changelog

• General improvement in splat quality
• Fix bug that causes floaters around objects when mask is present
• Add visualization for pixel error map (used to allocate splats during training)
• Support creating datasets from videos in OSV format
• Fix occasional crash

Notes:

• This release carries difference in training quality intended to be improvement. Please file an issue if you notice significant quality degradation compared to previous versions on your dataset.
• For datasets without strong lighting variation, training time can be reduced by a large factor by disabling bilagrid and PPISP. This is the case for this version as well as all previous released versions.

v2026.8.17

• Support for depth and normal generation using MoGe and Metric3D
• EXR file support + better support for linear and wide gamut color spaces
• Visualize SfM progress in GUI
• Fix occasional stall in Delaunay meshing
• Support side by side preview of multiple splats and meshes in GUI viewer
