Aura 0.4.0: Notes from the Build Room

This is a cross-post from https://www.ramenvr.com/studio-spotlight/aura-0-4-0-notes-from-the-build-room.

Version 0.4.0 is the largest release since launch. It’s a step function improvement in how it feels and today we’re excited to share the updates with you.

Much of this could not have been possible without the support and guidance of our Alpha Testers. A huge shout out to the community for your feedback and patience!

Speed that matters

Aura now answers significantly faster. In our internal projects we are seeing 2x to 3x lower latency on typical requests. The biggest contributor is our move to Cohere v4 embeddings, which improved both retrieval quality and cache hit rates. Less waiting, more iteration. That is the only speed metric that counts.

What this means for you: quicker design spikes, shorter iteration loops on asset pipelines, and fewer context swaps while you are in flow.

Agent Mode: let the tool do the boring parts

Today we are shipping a preview of Agent Mode. It can take concrete actions for you inside Unreal. It can create and edit:

• Data assets

• Structures

• Enumerations

• Blueprints

• Widgets

• Actor components

• Editor utility widgets

Assets can reference one another, so you can set up systems rather than isolated files. Two common uses from our tests: batch-editing large tables of assets, and generating data structures for complex inventories and crafting systems. Work that used to soak up an afternoon now fits between playtests.

Known limitation: blueprint graph editing and generation are not available yet. We are actively working on it and will share progress soon.

In addition to Agent Mode, there are two smaller helpers:

• Ask for quick questions where you want a focused answer.

• Analyze for deeper project reads where context actually matters.

Reasoning and web search

Aura now plans multi-step actions more reliably, which helps Agent Mode stay on task and improves answer accuracy. It can also search the web when needed, so it can pull directly from Unreal Engine docs, tutorials, and new API notes in UE 5.6. These integrations are still early, and we expect steady improvements over the next few months.

A tighter Unreal integration

Aura is more native inside Unreal. You can drag items straight into chat. Links from Aura jump you to the right place in the editor. Context menus let you ask for help on whatever you have selected. The end goal is simple: keep your hands in the engine and make the assistant feel like part of the toolset rather than a separate app.

Why we are building this

Games are a huge business, but most teams are small. A single designer or engineer can ship choices that touch millions of players. The tools we use shape what we try, how often we try it, and how quickly we learn. Our aim with Aura is to raise the floor on production work and leave the ceiling for your craft. More people building – with experienced teams moving faster with less friction.

We want tools that respect intent so you stay in creative control. The assistant does the repetitive work, exposes context, and gets out of the way.

If that resonates, we would love your feedback and your collaboration.
