I have a problem with applying materials to a landscape

I’ve been following A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums documentation of how to export from world machine to unreal but I have a problem when it comes to applying materials to my landscape. This is how my material looks like and I’ve tried to follow every step, It appears black

Hi!

I think you missed something. I was following this tutorial too and get this

Let me try again

I’ve tried and still have the same problem, when I connect a constant3vector to the base colour without using landscape layer blend it works just fine, but when I place the layer blend the overall material turns to black… I don’t know what to do.

I’m using version 4.9.2
