Engine or Game content [XXX] is being referenced by DLC!

My DLC pak file building process, working from v4.4 to v4.15, is not working on v4.17.

I get errors about referencing engine content.

Worth mentioning that the DLC plugin I’m testing this on has a single folder with 10 wav files in it, about as simple as they come.

Hi theonecalledtom,

I also meet this problem too, so I enable the checkbox of Include engine content inside the ProjectLauncher. And it helps me resolve the problem. Maybe you can give it a try.

I tried this, but it’s still “referencing” BP tutorials and AR Editor assets.
I checked in there reference editor and my DLC isn’t referencing any of that stuff.
Hmmmmmm

Same issue here. DLC is a plugin with 3 materials as basic as they can be. No texture reference or what ever. ConstVec3 as output color, that it. Did not even change settings of the materials.

We are also encountering this issue on 4.23. Any solutions or workarounds?
