Unity ships official plugins for Codex and Claude Code, Blender 5.3 alpha adds Gaussian splats

Fewer stories this week, but two matter if you build with AI agents or capture real places. Unity now has official plugins that teach coding agents how its engine works, Blender's next version is learning to load Gaussian splats, and Tokyo Game Show put numbers on how routine AI tools have become.

Unity ships official plugins for Codex and Claude Code

Unity released an official plugin for Codex on September 16, a week after its plugin for Claude Code. Unity says the Codex plugin bundles about 30 skills, packaged instructions written by the engineers who build each system, covering UI, 2D, rendering, audio, gameplay, monetization, multiplayer and localization, and tested against how the engine behaves.

If you are making your first Unity game with an AI agent, this should mean fewer answers that look right but use the wrong API. The plugins work with Unity 6 and later under the Unity Companion License, and you still need your own Codex or Claude Code subscription. They build on the Unity CLI and its MCP mode, which we covered in July.

Blender 5.3 is getting native Gaussian splat support

Blender developers merged native Gaussian splat support into Blender 5.3 on September 16. Gaussian splats are 3D captures made from photos or video, built from millions of soft, colored points instead of polygons. Blender will import PLY and SPZ splat files (plus USD splat particle fields), render them in Workbench, EEVEE and Cycles, and optionally make them relightable. That means a phone or drone capture could become a backdrop or a modeling reference without a third-party add-on.

The release notes are candid that performance is not ideal and rendering is not fully correct yet. It is in Blender 5.3 alpha daily builds only, not a stable release, so this is one to test, not to build a project on.

Tokyo Game Show gives AI tools their own pavilion

Tokyo Game Show 2026 opened on September 17 with a dedicated AI Technology Pavilion for its two business days, covering AI dev tools and middleware, content generation and character AI. Organizer CESA handed out a preview of its Game Industry Report 2026 at the show. According to Denfaminicogamer's coverage, 63.0% of surveyed developers use generative AI daily and 22.8% occasionally, 85.8% in total, up from about 51% last year. It is a signal rather than a product launch: AI tooling is now routine in Japanese studios. The full report is due in early December.

Also worth your time

• Unity opened the Unity 6.7 beta on September 17. 6.7 will be the next LTS (long-term support version), so this is the build to test your project against; Unity 6.6 remains the current release for shipping.
