If you got it to show in UE but the material doesn’t show the texture then you didn’t import them in the correct folders “fix up redirectors in folder” should fix this problem.
If you didn’t understand my original comment you have to manually move the actual uasset file inside your new project without using the engine import/drag and drop.
If the pack you’re using has a content folder that makes things even easier, you just copy everything from there and paste it inside your own content folder.
