Macro Library attempts to "recompile" at every startup

Development Programming & Scripting Blueprint
, , ,

Once per editor session, on the first play attempt, a macro library will attempt to recompile:

The recompile takes upwards of five minutes - it’s probably recompiling every single blueprint which references it, which is pretty much the entirety of my project, since it contains very basic macros.
Is there any workaround for this?

Hi aueron,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this error on my end?
  • Is this limited to one macro library or does it occur with multiple macro libraries?

Hi ;
The issue is limited to the specific library.

The issue persists in a blank slate project (With the specified library added!)
Project : (Including config, but in any case, please set “Editor > Play > Auto Recompile Blueprints” to false)

Hi aureon,

I was able to reproduce this on my end and have entered a bug report, UE-30612, to be assessed by the development staff. It appears that merely having the macro library in a project will cause the recompilation warning to appear. Unfortunately, at this time I do not have a viable workaround for the error.

We had the same issue and fixed it by moving our offending macro’s into a C++ Function library.
