3Dgs Render By Kiri Engine

3D Tools by KIRI Engine in Rendering

Gaussian Splat assets combined in Blender with 3DGS Render

Free & open-source Blender add-on

Bring Gaussian Splats into Blender.

Import 3DGS .ply files, clean and style splats with familiar Blender tools, build mixed mesh-and-splat scenes, animate through proxy geometry, and export the result.

From captured splats to a Blender scene.

Import, edit, render, rig and export without leaving the Blender workflow.

How it works

One add-on. Three connected workflows.

Edit

Import, select, crop, reduce, recolour, paint and apply modifiers.

Render

View and output splats alongside native Blender scene elements.

Create

Try proxy animation, lighting, .ply sequences and mesh conversion.

Core workflow

Edit splats with Blender tools.

Treat your scan as part of the scene, not as a locked result. Remove unwanted splats, isolate regions, adjust colour, apply camera culling and build stylised effects with familiar selection and modifier workflows.

Core workflow

Render splats alongside Blender scenes.

Move between an editable mesh-based view and a dedicated splat render workflow. Compose 3DGS content with native Blender meshes and use the result for stills, animation and VFX experiments.

Experimental

Proxy rigging

Animate splats through proxy geometry.

Bind a smaller object scan to proxy geometry, animate that proxy with an armature, lattice or another deformation workflow, then transfer the motion back to the splats. Bake the result for rendering or export it as a .ply sequence.

Help test the update

Try the improved rigging workflow and tell us how it performs.

The updated proxy-binding method is designed to improve deformation transfer and speed up baking. Results still depend on the scan, proxy mesh, settings and motion, so testing across a wider range of real projects will help the community improve it. Please share reproducible successes, comparisons and failures through GitHub Issues.

Experimental

Lighting workflows

Explore relighting and light baking.

Experiment with integrating splats into new lighting. The add-on includes proxy light baking, while recent community work adds real-time relighting and mesh shadows to the real-time render workflow.

Animation export

Edit in Blender. Carry the motion onward.

Export geometry changes and baked animation as numbered .ply sequences for 4DGS-style workflows and compatible external tools.

Project update

Free, open source and moving into community maintenance.

KIRI Engine created and maintained 3DGS Render as a free community tool. KIRI Engine is now inviting trusted maintainers and contributors to help review changes, test compatibility and prepare future releases, while remaining the repository owner and project steward.

Before you download

Check GitHub for the current release.

Community development may move faster than this listing, KIRI Engine's written guide or older YouTube tutorials. Before choosing a package, check the matching GitHub release notes for supported Blender versions, changes and known issues.

Most artists should use a packaged release. The repository's main branch may contain newer work that has not yet been packaged or fully tested. Direct support and response times are not guaranteed for this free, community-maintained project.

Added Blender 5.2 support, experimental real-time relighting and mesh shadows, helping splats react to scene lighting and blend more naturally with Blender geometry.
