The hangar door in L_Airbase won’t budge when I press E. Why? Make it kick open and keep the slam sound.

It’s a Static Mesh, so nothing listens for the kick. I’ll add BP_KickableDoor with a kick event, a Timeline swing and SFX_DoorKick.

Sound: a heavy kick and the door slamming open, gunfire echoing through the hall, long bursts of rifle fire and casings ringing on the concrete.
Answers from your Unreal project, not guesses.
Every Blueprint, C++ class, asset and level in your Unreal Engine project, with every reference between them, synced in the background as you work. Ask about BP_Door and the answer starts from ADoorBase, not from a generic tutorial.
A sample Unreal project of 448 files: Blueprints: 110, Widgets: 44, Meshes: 72, Materials: 54, C++ classes: 63, Animations: 35, Levels: 15, and Sounds: 55.

Ludus runs inside the Unreal Editor and reads your whole project. A general AI tool sees only what you paste, an MCP connector only what each call returns.

“No tool is magic, but Ludus AI gets very close for UE work. It doesn’t replace expertise, yet it accelerates debugging, code generation, and scene prep so much that it feels unfair.

Enterprise
Ludus for your whole studio
Built for the work standards of AAA productions. Custom credit volume, a private cloud option and a dedicated team help you roll Ludus out across every project and seat.
Ludus is independently certified to ISO 27001 and SOC 2 Type 2, and fully GDPR compliant. Your code and data are never used to train AI, never sold, and stay with you.
Ludus AI is an AI toolkit for Unreal Engine 5 that works inside the Unreal Editor and knows your whole project. It generates, explains and debugs Blueprints and C++, answers UE5 questions about your own project, and makes 3D models, VFX, sound, materials and animation, so the tedious and the tricky parts go faster and your time goes to the creative side.
02Will Ludus make my game for me?
No, and it is not meant to. You make the game; Ludus takes the tedious and the tricky parts off your plate. It answers questions about your project, helps you prototype, traces bugs across Blueprints and C++, cleans up tangled graphs and makes 3D models, VFX, sound and materials for you to tweak. It proposes each change, and you decide what goes in.
03What happens when the trial ends?
Pro continues at $25/mo, or $20/mo if you choose yearly billing. We email you 3 days before the trial ends, and you can cancel in one click from Settings.
04Why do you ask for a card?
Only to stop trial abuse. Nothing is charged during the 14-day trial.
05Does it work with my existing project?
Yes. Ludus runs inside the Unreal Editor on Unreal Engine 5.4–5.8, on Windows, macOS, and Linux. It reads your Blueprints, C++, assets and levels, so answers and changes fit the project you already have.
06Blueprints, C++ or both?
Both. Ludus reads, explains and edits Blueprint graphs, Behavior Trees, widgets and materials, writes and refactors C++, traces an error across both, and can move a prototyped Blueprint to C++ when performance calls for it. You approve every change.
07Is my code safe?
Ludus is independently certified to ISO 27001 and SOC 2 Type 2 and is GDPR compliant. The trust center explains how your code and data are handled.
08What are credits?
Every request uses credits, and bigger tasks use more. Pro includes 70,000 credits a month, Studio 250,000 per seat and Ultimate 600,000 per seat. Paid plans can add credit packs that never expire.
09Is there a free plan?
You can create an account for free, but the Free plan has no credits, so the agent needs the Pro trial or a paid plan to run.
10Can my team use it?
Yes. Studio and Ultimate share one credit pool across seats, with roles and invites. Managers who only handle billing join free.
11How is this different from a general AI tool or an MCP connector?
A general AI tool sees the one graph you paste. Ludus works inside the editor and syncs your whole project live, so it knows how your Blueprints, C++ classes, assets and levels work together, and its answers and edits fit that logic. Compared with a standard MCP setup it is up to 10× faster and up to 6× cheaper, depending on the task.
12Which operating systems and Unreal Engine versions does Ludus support?
Ludus runs inside the Unreal Editor on Unreal Engine 5.4–5.8, on Windows, macOS, and Linux. After signing in, download the installer from the Plugin page. One installer finds every engine on your machine and adds the matching plugin build to each, so there is no version to pick and nothing to unpack.
13How are credits used in Ludus?
Every request to Ludus uses credits, and bigger tasks use more. Each time you send a message Ludus re-reads the conversation for context, so clear prompts and focused conversations use fewer credits.
14Do credits roll over to the next month? What about credit packs?
Subscription credits do not roll over: they last until the end of your billing cycle, and on a yearly plan they renew every month. Paid plans can buy credit packs, and credits from packs never expire.
15Can I upgrade, downgrade or cancel at any time?
Yes. When you upgrade, the unused part of your current plan is credited toward the new one. A downgrade, or a switch from yearly to monthly billing, takes effect at the end of your billing cycle, and so does a cancellation. You can also cancel during the 14-day trial, before the first charge.
16What is the refund policy?
Subscription payments are generally non-refundable, which is why Pro starts with a 14-day free trial. If you believe credits were deducted because of a bug on our side, email support@ludusengine.com and we will look into it.
17How do I check my current credit balance?
Your current credit balance appears under your username. Open Credits in the app for detailed usage information.
18What does a pending payment mean?
The payment has started but has not completed yet. Allow up to 20 minutes and check that your payment method is valid. Contact support if it stays pending.
