Megascans Issue

Hello all,

I was just testing out some foliage assets from Megascans but when I imported them they looked like this:



I've tried fiddling with some settings but I couldn't get anything to change the way they looked...
I tried 2 different projects, and one of them the colour was more pronounced - but I literally did the same things in each project so I don't know what happened there.
Do they need a Metallic setting maybe? I noticed they don't seem to have one.

If anyone has any ideas I'd very much appreciate it!
