v1.5: The Antigravity Update

🚀 v1.5: The "Antigravity" Update

Unlock the full potential of Gemini 3 on Windows.

We are thrilled to bring you v1.5, a milestone release that bridges the gap between advanced AI agents and Unreal Engine.

✨ Highlights

🌌 Antigravity Support (Windows)

"You can now watch the Gemini 3 ability."

We've cracked the code for Windows compatibility!

• Zero Friction: No more "invalid trailing data" errors.
• Seamless Integration: Our new antigravity_wrapper.py ensures your AI agent talks perfectly to Unreal Engine, strictly adhering to the JSON-RPC protocol.
• Ready for Action: Just update your config and let Gemini drive.

🎬 Animation Sequencer (Beta)

"Some of Animation Sequencer is able."

The foundation for AI-driven animation is here.

• Initial Toolset: We've started exposing the Sequencer API to the MCP.
• Work in Progress: This is a preview of what's to come—programmatic control over your cinematics and UI animations.
