Yarin AI is a plugin that adds an AI agent inside the Unreal Editor. You type what you need in a chat panel, and Yarin does the work directly in your project: code, Blueprints, assets and translations.

What it does

• Knows the whole engine. C++, Blueprints, Anim Blueprints, widgets, materials, GAS, Git. It reads your project and answers in context.

• Edits your project for you. It creates and modifies C++ files, Blueprints and widgets, and shows every step in the chat.

• Multiple agents in parallel. Run several agents at once, all working on your project at the same time.

• Knows ACF. It has full knowledge of Ascent Combat Framework. Included with ACF Ultimate

• Generates images. Concept art, textures and UI images are created from the chat and imported into your Content folder.

• Generates 3D models. Go from prompt to concept, and from concept to 3D mesh, with Meshy. Rigged humanoid skeletal meshes are also supported (experimental).

• Localizes your whole game. Every FText in your localization target is translated into the cultures you choose.
