Luckily the dev kit is freely available to anyone to use, for making Ark/Unreal mods and for learning purposes. I do believe you will run into the issue of needing a separate Steam account for each system. But as long as you don’t use the assets in another engine or for a commercial purpose you should be free to use it as a teaching example. This should include exporting the assets for editing in another program. (I do not work for Unreal or Studio Wildcard, so my statements are not their voice, and could be incorrect - but I believe you are on safe ground with a legal and respectable use of the material.)
Just because Epic freely allows educational use of their engine doesn’t meant the same license extends to anyone wanting to use Studio Wildcard assets. They are owned by Wildcard not Epic. In addition to this Wildcard makes use of some third party products, which have their own license terms.
Your best bet would be to email Studio Wildcard and ask.
