Hello,

I made a custom material I will be using for my landscape. When I try to apply it to the landscape I get an error saying LogMeshMerging: “Material Ground” is missing required parameters…

I have never had to use all the parameters in the past. Any idea to why this is happening?

Thank you for the assistance.
