I might have some missing textures

I’m new to using unreal engine and I wanted to know how can I fix my build since it’s all green. I was told that I might be missing some textures and that I should as my question here.

Hello CoD4Lyfe,

I would like a little more information from you regarding this issue.

1.) If you would link me your DxDiag?
2.) Does this happen in 4.8?
3.) Do you have enough space where you have your project, say your C: drive, to run UE4?
4.) Does this happen in a new blank project?

After I have this information I will be able to narrow down what could be causing this.
