360 Splat Pro v1.2.5: GPU-Friendly Alignment and Insta360 Raw Photo Support

Ronski has been quick to ship continuous updates to his 360 data plugin for gaussian splatting. He just shipped versions 1.2.0 and 1.2.1, adding RealityScan mesh generation, Qoocam support, and GPU workflow controls that made the pipeline more flexible.

What the 1.2.x updates didn’t address was alignment speed on best quality presets, or the growing number of users reporting GPU detection issues on RTX 50-series hardware. Version 1.2.5, released over the weekend, closes both of those gaps, and adds native support for Insta360 raw still photography along the way.

The most significant change is the introduction of a GPU friendly mode on the Align tab. Feature extraction, the step that precedes COLMAP and tends to dominate Best Quality alignment time, has historically been the slowest part of the pipeline. Ronski reports that on a 3080 with 8K footage, Best Quality alignment previously took around 5 minutes 45 seconds. With the GPU friendly mode enabled (it’s on by default), that drops to 1 minute 59 seconds, roughly a 3x speedup. For power users who prioritize maximum match quality on difficult drone or wide baseline footage, the mode can be toggled off, with a tooltip explaining the trade off clearly.

Alongside the performance work, v1.2.5 also fixes a hardware detection bug that had been affecting RTX 50-series owners. An outdated architecture check in the status bar was incorrectly flagging Blackwell GPUs as “CPU SIFT only,” denying them GPU acceleration during feature extraction. After the fix, 50-series users will see the expected green GPU indicator and get the full acceleration they’re entitled to.

On the capture side, 360 Splat Pro now supports Insta360 Raw Photos, specifically .insp still image files. The original launch focused on video workflows (.INSV from Insta360, .OSV from DJI Osmo), but still captures were unsupported. The new “360 Insta Stills Raw to 3DGS Trained” workflow accepts multi selected .insp files, splits each into front and back fisheye, applies masking, and runs alignment through COLMAP, the same pipeline as video, applied to stills.

A handful of workflow reliability fixes round out the release. The SAM3 masker now correctly auto-detects GPU precision on RTX 20-series cards, with bulk masking via “Mask All” confirmed working on Ampere hardware. Align tab presets now persist across restarts. Previously, tweaking a value and relaunching the app would silently revert the change. Editing alignment fields like Features or Max Img Size no longer quietly resets other parameters to a different preset’s defaults. The point cloud viewer now auto refreshes to show the densified cloud after running Cubemap with Improve Points. And when Sequential matcher is paired with SphereSFM alignment, a known incompatibility, the app now surfaces a clear “Use Exhaustive” message rather than silently producing zero matches and a mapper failure downstream.

Version 1.2.5 is available now to existing purchasers via Gumroad. 360 Splat Pro remains a $44.99 one-time purchase with all v1.x updates included through 2026.
