I need help finishing creating an auto landscape material.

Hi I’m fairly new to Unreal and I’ve been following this youtube tutorial on how to create an auto landscape material and it isn’t going so well. I’m nearly at the end and I have the material created, but it looks a lot different than what his looks like… This is what mine looks like and this is what his looks like.


(the other picture will be posted later I can’t post two at the same time)

This is the link to the video. I’m currently at the timestamp 2:45:39

If anyone can help me please let me know.
