I've bought dozens of the Kitbash packs, they're great, love the content, but the workflow with Cargo is just unbearable.
It's fine if you are loading an entire pack, you just trigger the import, go to lunch while the software imports the whole pack, but loading content from Cargo is just painfully slow - when it works.
I clicked 'import' on a single model from a pack and 15 minutes later Unreal is STILL processing files - and even worse, cargo doesn't give any kind of progress to indicate how long this import might take.
This is such a downgrade from 'just using the packs' that we used to be able to do that it makes me sad.
