MWLandscapeAutoMaterial - Landscape Visibility

Hello
I wanted to toy around with making a hole in my landscape, I’ve used the Landscape Visibility tool in the past for this.

My problem this time, I believe, is I am using an auto material from the marketplace, MWLandscapeAutoMaterial, it’s a great material but a little too complex for me to solve directly so I came for some guidance if possible.

The actual problem I think is the way I have hooked up the landscape visibility within my landscape hole material. I simply copied the base auto material and then plugged in the node they already had available into the opacity mask within the make material. I also set the hole material to a blend mode of masked.

That leads to this effect within the cell I’ve applied the texture to within my world partition.

I am no material expert, obviously hah, would someone be able to help guide me to correction please?

Thanks in advance.

I found I was able to get this to work by not creating a separate hole material and just using the OpacityMask directly within the main material.
