Hi maintainers and community,

I've been maintaining an active fork at https://github.com/hummat/sdfstudio with significant improvements over the current upstream. Since there hasn't been activity here since 2023, I wanted to make the community aware of this alternative for anyone looking for:

Key Improvements

Modern Compatibility:

• PyTorch 2.0-2.5 support (from 1.12.1)
• Python 3.9-3.11 support
• RTX 40XX GPU support (sm_89+)
• nerfacc 0.5.2
• Automatic TCNN fallback when tiny-cuda-nn unavailable (fixes How to use sdfstudio without tiny-cuda-nn #290)

Bug Fixes from upstream/fix branch:

• Test pose normalization with proper index filtering
• Full resolution image loading for DTU datasets
• High-res foreground mask support
• Corrected auto_scale_poses and auto_orient defaults

New Features:

• PBR texture export (roughness, metallic, ORM maps for glTF)
• Tangent-space normal maps
• sRGB-linear basecolor handling
• Modern CI/CD with uv
• Lazy loading of optional dependencies
• Comprehensive test coverage

Documentation:

• Agent/development guides
• PaperPipe integration for paper references
• Updated testing patterns

For Maintainers

I'm happy to submit PRs for any of these improvements if there's interest in merging them upstream. I can start with smaller, self-contained fixes like the TCNN fallback or PyTorch 2.x compatibility if that would be helpful.

For Users

If you need a version that works with modern GPUs and dependencies, the fork is production-ready. All original functionality is preserved with additional features.

See the fork's README for full details: https://github.com/hummat/sdfstudio#fork-improvements-2024-2026
