The engine won't allow you to import DXT. You might also have to set the mipgen settings to LeaveExistingMips
When a user attempts to create a .dds file using nvidia texture tools and saves it with custom mipmap settings, the resulting file fails to import into the engine.
Expected: the file will import without issue.
Acutal: the file fails to import with the following message:
Failed to import 'C:\Users\Benjamin.Hyder\Desktop\BrickWallSimple.dds'. Failed to create asset '/Game/Developers/BenjaminHyder/BrickWallSimple'
Note: I attempted to import this to my developer folder.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-24529 in the post.
