KIRI Engine has released Version 4.1 of its 3DGS Render add on for Blender. What started as a routine bug fix update turned into something larger, adding a mix of long requested features, small experiments, and quality of life improvements.
KIRI has continued their approach of leaning more toward how artists actually use them. Version 4.1 continues that pattern, practical updates that make splats easier to work with, and small steps that invite creative exploration.
The new Adjust Attributes modifier exposes internal data from each 3DGS scan. Most users won’t know what Spherical Harmonic degrees refer to, but changing the values and watching what happens creates a more hands on way to understand how splats behave. Having more easy to visualize sliders should go a long way to translate otherwise technical concepts.
Another addition lets users quickly convert a scan into a coarse mesh. It’s not detailed enough for modeling, but it’s useful for physics collisions, shadow casting, or serving as a crop box object, things that make splats easier to integrate into broader Blender workflows. This is an exciting emerging workflow, as people continue to ask, where is the mesh?
A third feature, Auto Generate Crop Object, automatically creates a new object based on the most focused region of a scan. It’s the kind of “auto” feature non technical users have been asking for, and it works well as a starting point that can be fine tuned later.
Beyond those, the release includes a handful of smaller updates. A rotate for Blender axes shortcut, four new crop box modes, a memory saving option to remove higher SH values, and expanded debugging tools.
Version 4.1 continues KIRI’s steady progress toward making gaussian splatting natively in Blender usable for day to day work. Both as a renderer and as something you can explore and learn from. The add on remains free under the Apache 2.0 license and can be found on GitHub and SuperHive.
