Blueprint not updating C++ comments on compile if the node existed in a graph pre-compile

Development Programming & Scripting Blueprint

So I just went through some old code and added comments to a bunch of stuff. I noticed that if a node existed before the re-compile then the comments won’t show on that node, whereas if you place a new node of the same type then the comments will show. Also, the function it’s self hasn’t changed.

Here’s an example:

Hi pdylanross,

I ran some tests to try to reproduce this issue. I was able to find something similar, but not the exact issue that you described. Would you be able to provide more information?

  • What version of the Engine are you using?
  • Are you using the binary version of the Engine installed by the Launcher, or did you build the Engine from source code?
  • Could you provide the code where you add your comments and function declaration in the header file?
  • Are you re-compiling the project in Visual Studio with the Editor still open in order to perform a Hot Reload?

Hi pdylanross,

I have entered a report about pin comments not updating on existing nodes in order to have this investigated further (UE-6586). Please let us know if you need any additional help with this issue.
