Packaging fails due to Landmass materials

Development Platform & Builds

Hi, I recently started testing packaging my project and I got the classic “Unknown Cook Failure”.
For starters, I want to package just one level, which was converted to a world partition type of level. In this level, I have a landscape for which I activated the Landmass plugin. Now, the Errors from Log point to M_BrushSprite_01 and BrushBounds, from the Landmass plugin, as the culprit since it has a reference to some engine assets, but I looked into the Reference Viewer, and no actor or asset has references to these material. I don’t understand why Unreal is trying to cook it.
Any way to solve this?

Here is the Log:

Got the same error. Did you find out how to solve this?

I fixed the issue under packaging → “exclude editor content when cooking” and set it too false
For some odd reason I am using editor content

Arr well, I did solve this by going in and remove all the editor-related assets.

For some wierd reason, I never had this issue before. (Can’t have editor asset tagged along either. On tight harddrive budget here for mobile.)
