Any thoughts?

still need help

Bumping still need help

fixed by removing content folder and re adding

Hey jaayvazian,

I was wondering if you had any idea what may have caused this in your content folder. I’ve tracked down the issue in our system and it’s happening with a few other users.

We suspect it could be related to trying to open content that was created in a newer engine version.


Not sure since it works with the same files in it, I just moved the folder in and out and it seemed to work.

I had the same issue. Deleting the intermediate folder solved it.

I had it after a pull from our repository (we’re using the same engine version).
Seems like it has some issues updating the shaders.

FYI when this happens you should only have to delete CachedAssetRegistry.bin from your Intermediate directory to accomplish the same workaround

Im gonna bump now. I have deleted Binaries, Intermediate, saved, Derived data cache folder and replaced my blueprints and also rebuilt my entire engine. What now ?
