Hey there @Tom2201! If we’re trying to avoid Pak files, know that cooked data won’t be available without using the Pak tools themselves, but your use case as a product configurator and not a game, that limitation shouldn’t be too much of an issue thankfully.
In previous versions of Unreal I used to use a much older version of the (Free) Runtime Mesh Loader plugin back in UE4. It looks like this is a partially updated fork that might still work but your mileage may vary. Though some users have recommended the (Paid) gITFRuntime plugin instead, but I haven’t used it myself.
