What happened?
When an agent via Github copilot attempts to create a custom event with a float parameter, it gets translated to float (single precision) on UE 5.7.4, which is not a valid type in Blueprints.
Therefore, the custom event fails to compile, requesting a refresh and stating it is out of date. Details panel show the variable as float (single precision) while the event never compiles and param can not be linked
What did you expect to happen?
Custom event created with correct float type that compiles
Unreal Engine Version
UE 5.7
MCP Client
VS Code (Copilot)
Environment Information
- OS: Windows 11
- MCP Server Version: 0.5.20
Steps to Reproduce
- Ask Haiku/Sonnet/GPT5 to create a custom event, with a float param, connected to a delay or print string
- It gets stuck, make sure to have a fail try count so it does not loop
- click on the created node in the graph to see incorrect pin type
