Marketplace plugins skipped during packaging project in source built engine.

I have marketplace plugins working in editor, but when I package my project it “skips” the marketplace plugins and errors out complaining that the plugin isn’t there (obviously because it was skipped).

What I have done:

  1. Installed launcher engine 4.25.4
  2. Downloaded marketplace plugins and installed to launcher engine 4.25.4
  3. Built source engine 4.25.4 (oculus branch as I need quest 2 compatibility)
  4. Copied marketplace plugins to source engine
  5. Built source again
  6. Launch project agreeing with warnings/errors
  7. Enjoyed plugins in editor and preview
  8. Packaging fails throwing a bunch of warnings and errors
  9. Question my life choices that lead to this moment and resist the urge to build a cabin in the woods far away from any technology…

The warning/error when I launch project:
“The ‘xxx’ plugin was designed for build 4.25.0. Attempt to load it anyway?”

And when I package the log warning:
LogPluginManager: Warning: Plugin ‘xxx’ is not compatible with the current engine version (4.25.0)
LogPluginManager: Display: Skipping load of ‘xxx’.

I am confused as to why the plugins work in the launcher and not source of same version, but ultimately would just like to get this project packaged.

Running into the same exact issue, but im on Oculus 4.25.3

Ever find a solution to this, I’m in the same boat.

Has anyone found a solution for this? - I also find myself in the same predicament.

To anyone that may be having similar issues, I managed to resolve it by doing the following:

Open XXX.uplugin with VS [Your preferred version of Visual Studio]

Remove the following line completely: “EngineVersion”: “4.26.0”,

Save and then rebuild. It worked for me, I do hope it helps others as well :slight_smile:


I was about to give up and start a bakery or something but I can confirm that his still works.

Exactly same warning for the packaging. For my 4.27.2 engine, I changed the engine version in .uplugin to 4.27.0, and it works now. Seems like we need to ignore the patch version.
