Hi there, I’m new to unreal engine and have been following tutorials on material creating and putting them on objects. After following each step correctly however, my preview for the material doesn’t show the changes in colour etc and neither does the objects. They just stay the same with the default no texture material.Am i doing something wrong or is it a problem with my system? Please help.
-Have you clicked on the apply button?
-have you connected something to the “base colour”?
-have you added the material to your object? 
-could you post a pic of your material setup?
hit that ‘live preview’ - button, son ! (you might have to close down mat editor , or do some other stuff before it takes effect)
