UDN: [Link Removed]
A UDN customer has observed that their cooked materials have doubled in asset size going from 5.1 to 5.2.
We need to investigate this is only a local issue on their side and not a systemic problem.
Edit: the UDN case has been updated with sample material files to help debug the issue. Attached are the files for convenience..
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-190497 in the post.
