Title

Initial implementation of AI Assistant. I recommend using the qwen family but any model with tools support should work.

Screencast.From.2025-11-17.13-08-09.mp4

Summary

Add a new tab called AI Assistant where the user can send messages to a LLM to modify the scene. Currently only local Ollama is supported and it can only modify meshes, materials, lights and cameras.

It is still in very early stages but shouldn't be hard to add more features from there.

Changes Made

Creates a new tab AI Assistant with a chat interface.

Integration with Ollama using langgchain

• Added langgchain tools to the project
• Added integration with ollama

Benefits

Users can use LLMs to modify the scene

@yuripourre did you try the idea you had to have more "common way" to handle actions?

[yuripourre]

@julien-moreau no, I thought about it a lot and I think the current implementation would be better long-term. The reason is, the tools would be separate by the type of element.

We spoke about having this as an external plugin, maybe it's the way to go.
