BP2AI - Unreal Blueprint to Text
Ai excels at text analysis but can't read visual Blueprint graphs efficiently at scale till now.
BP2AI solves this by converting Blueprint Logic and Data Flow into accurate AI-Readable Text,
enabling instant context transfer to AI Large Language Models under your control.
What is the BP2AI Translator?
A Precision Translator, Not a Code Generator.
✅ WHAT BP2AI IS:
- Blueprint-to-text translator
- Accurate logic & Data representation
- Complete context provider for AI analysis

Hello,
Thank you for building BP2AI. I wanted to share some feedback after using it extensively for actual Blueprint debugging and revision work.
At the moment, I am running into too many mismatches between the BP2AI output and the actual Blueprint graph, to the point that it becomes difficult to use the output as a reliable reference for debugging or for communicating edits to someone else.
The main issues are:
1. The node names in the output often do not match the node names shown in the Blueprint editor.
For example, nodes that are visibly MIN / MAX in the graph are described as FMin / FMax in the exported output, and Set Timer by Event is described as K2_SetTimerDelegate. This makes it much harder to map the output back to the real graph and identify which node should actually be edited.
2. Function / Event classification is not reliable enough.
For example, something that is clearly exported as a FunctionEntry can still appear in the body as “Event DoAttack,” which is misleading when trying to locate the real implementation in Blueprint.
3. The output tends to expand internal expressions instead of preserving the actual visible graph structure.
In practice, this means that intermediate nodes that are clearly present in the Blueprint editor become harder to identify in the text output, because the export favors internal-style expression expansion over the editor-facing structure.
4. Internal or engine-style naming is too prominent.
Names like K2_*, ValueFrom(...), and similar internal representations may be technically accurate, but they do not correspond closely enough to what a user actually sees in the editor. That makes the export much less useful for day-to-day Blueprint troubleshooting.
The practical problem is that these mismatches are large enough to cause real miscommunication. In my case, they already led to incorrect assumptions during debugging, because the exported text suggested a graph structure or node identity that did not actually match the Blueprint I was looking at.
I think the tool would become much more useful if it prioritized:
* the exact node names shown in the Blueprint editor,
* strict distinction between functions, events, and custom events,
* preservation of visible intermediate nodes,
* and less reliance on internal engine-style names in the default export.
I believe the tool has a lot of potential, but in its current state the mismatch between the exported representation and the actual Blueprint graph is too large for dependable debugging use.
Thank you for your work, and I hope this feedback is helpful.
Hello. i tried to instal in 2 engine 5.6 and 5.7 but nothing show up in any project
Hi, I’m finding BP2AI very useful overall, especially for execution flow and reroute/shared-path tracing, but I found a specific export issue.
In UpdateCameraDistance, the exported text appears to omit the Target input pin on FInterpTo. In the actual Blueprint, that Target pin is wired from a Map Range Clamped chain driven by GetSpeed and related min/max variables. Because the Target pin is missing in the export, that whole upstream logic is also missing from the text, which changes the meaning of the function.
I’ve also noticed that reused pure/data nodes can sometimes be inlined as if they are re-evaluated multiple times, even when the Blueprint graph only calls them once and then reuses the result. That part is less serious, but the missing FInterpTo.Target pin seems like a real accuracy bug.
Overall I like the plugin, but could you please check whether FInterpTo input serialization is dropping the Target pin in some cases?
Thanks Kazu for the Proposals. I will contact you via mail for some more detailed Information.
“If I may point out a couple of small inconsistencies: BP2AI is a function, but it’s occasionally described as a Custom Event. Could we align the terminology there?”
“And regarding Set nodes: connecting a value into a Set doesn’t necessarily imply the logic is being evaluated twice—it’s typically just one value feeding the assignment. It might be best not to call it ‘double calculation’ unless there’s clear evidence.”
Hey Petro, thanks for your comment. I updated the Plugin to support also Wait Events like "Wait Gameplay Event".
Hey. Nice plugin but figured out that not all params are serialized for some nodes. For example "Wait Gameplay Event" are not including tag
