Ark Dev Kit no textures

I’m new to using the dev kit so sorry if this is obvious. I have started making a small map to get used to how it works and learn how operate it. though i noticed that in the video I was following the static mesh had an actual texture while mine was the same color as the ground. When I tried to change it nothing would get it to switch textures. I then tried to go and paint my ground to make it stand out and found that the paint toll also wouldn’t change the ground texture. so far nothing I have tried will get any of the textures to change off solid black. I couldn’t find anyone with a similar problem on here so it posted this. If someone knows how to solve this I would appreciate it very much.
