Changelog

Release notes for the Cosindra desktop app (Windows & macOS). The app updates itself automatically — this page is the record of what each update brought. Download the latest version.

v1.3.3

LatestSeptember 6, 2026
  • Fixes a crash at launch in 1.3.2. If 1.3.2 will not open on your machine, download this version and install it over it — your settings and sign-in are kept

v1.3.2

September 6, 2026
  • MaterialForge inside the app: generate a whole material pack from one brief, then apply packs and adjustments straight into your project as material presets
  • WorldWeaver can now request the materials a world needs and hand them to MaterialForge
  • New Niagara tools for the AI agent: build particle systems from scratch, not just canned presets
  • Texture and material tools: import textures with correct map types, set texture parameters, create material instances, assign materials — and a delete that checks references first
  • Sturdier project setup: a plugin update no longer touches the project while the Unreal Editor has it open, and the app tells you to close the editor instead
  • The local server is now a shared service: the desktop app and the new VS Code / Cursor extension can drive the same editor session
  • Diagnostics: the local server log now lives in the Cosindra data folder, in one place for every platform

v1.3.1

August 5, 2026
  • Reliable editor connection: ports are now assigned automatically, so another app using the same port can no longer block or crash the connection
  • Fixed: creating an account inside the setup wizard left the app signed out until the next restart
  • Browser prompts now correctly say "Open Cosindra?" when applying from the website
  • WorldWeaver: rectangular worlds build true to the preview, terrain arrives fully colored, and building a new world no longer risks an editor crash
  • Better connection diagnostics so setup problems can be found and fixed faster
  • AI agents (bring-your-own-key): accurate per-agent modes, a usage panel, tidier commands, and Gemini/Cursor setup fixes
  • Template fixes that ship with the app: day-night cycle actually cycles, atmosphere presets aim the sun correctly, sturdier template runs

v1.3.0

July 21, 2026
  • Apply Blueprints directly from web share and gallery pages
  • Save-guard prompt protects unsaved editor work before applies
  • Automatic rename-and-retry when an asset name collides
  • Clearer hints when the app and the website are signed into different accounts
  • Model selector in the assistant
  • Plugin 1.2.0: editor screenshots can include the UI, voice import, auto-created Event Graphs, better text pin defaults, widget tree inspection, hardened WebSocket auth
