Nothing shows in the ref i feel this is a bug with uefn and i need someone at Epic to reset something in the uproject file ?

Well thanks to the ai bot i was able to find a ref to that asset it was an epic internal texture and for some reason when i ref a instance of the barrier mat in verse it through this error out.

Unsure why i had an error on a instance of the mat. I then uncommented it out again and it works so makes no sense to me but yea this is working now :slight_smile:

It randomly keeps erroring when i try to launch session. Sometimes it launches fine sometimes it errors. These 2 materials are instances of the Epic barrier material (The blue and red versions) Invis is my own.

The 2 Epic instances keep triggering the error above. Now i know i simply comment them out then build verse then un comment then it works again but can someone look into this. I dont know why its causing errors when using an instance but could cause issues due to these materials being used by many people in the same way ie instance

The 2 materials i have created instances from

My Instances - Changed color slightly but don’t think that’s the issue here
