Use Cases — NodeLens for Unreal Engine

🚀

New Project

Starting out and hitting a wall

You know what you want to build. You follow a tutorial, set everything up exactly as shown — and something still doesn't work. Or you're building from scratch and reach a point where the logic just won't cooperate.

Send your Blueprints to NodeLens via the UE5 plugin.

Ask the AI what's wrong — "I followed a tutorial for an inventory system but items aren't being added. Can you check my Blueprint?"

Get a clear explanation of what's missing or misconnected, and how to fix it.

Result: Instead of spending hours comparing your nodes to a video frame by frame, you get a direct answer in seconds.

Existing Project

Understanding what you already have — one function or the whole codebase

You've been working on a project for months. Some Blueprints are complex and you're not sure what everything does anymore.

Send your Blueprints to NodeLens via the UE5 plugin — takes a few seconds per Blueprint.

Ask "Give me an overview of what this Blueprint does" or "Walk me through this function step by step".

With Claude via MCP, you can ask about a single function, a specific Blueprint, or your entire project at once — variables, components, and all. With other AI providers, you send Blueprints one at a time through the plugin.

Result: Full understanding of any Blueprint in minutes — even ones you didn't write, even across the entire project.

Debugging

Something isn't working and you don't know why

The game runs but items disappear, the character doesn't respond, or a function silently does nothing.

Send the Blueprint to NodeLens and ask "Is there anything in this function that could cause items to stack incorrectly or disappear?"

The AI analyzes the full graph — checking conditions, exec flow, and data connections — and returns a prioritized bug report.

Ask it to write a corrected version and save it directly to your project's Fixes folder.

Result: Bugs identified and explained in seconds — with a fixed version ready to compare against your original.

Code Review

Reviewing Blueprints you didn't write

You inherited a project, hired a contractor, or are onboarding onto a team. You need to understand the codebase fast.

Import the entire project into NodeLens at once using the folder import feature.

Ask "Which Blueprints depend on the inventory system? If I change how items are stored, what else might break?"

Get a full dependency map and risk assessment before you touch a single node.

Result: A clear picture of the entire codebase — who calls what, what depends on what, and where the fragile parts are.

⚙️

Refactoring

Improving logic that works but could be better

The function does its job but it's messy, hard to read, or doing too much in one place.

Send the function to NodeLens and ask "Is the logic in this function correct? Are there any improvements you'd suggest?"

The AI explains what the function does, identifies any redundancy or edge cases, and suggests a cleaner approach.

Ask it to write the improved version and save it alongside the original so you can compare both on the Canvas.

Result: Cleaner, more reliable Blueprint logic — with the original untouched until you're ready to switch.

💡 A note on AI providers

NodeLens works with Claude, ChatGPT, and Ollama.

With Claude and MCP, you can let the AI automatically explore and read your entire project — Blueprints, functions, variables, everything — on its own.

For other models, you simply select and add the specific Blueprints or functions you want the AI to analyze.

Even if you don't keep it, you'll have a clear picture of every Blueprint in your project.
