Why will my landscape visibility tool only work sometimes?

For sure!

I have duplicated my landscape material and set the duplicate’s Blend mode to masked in order to create a “hole” material where I plugged in the Landscape Visibility Mask node to every texture’s Opacity Mask.

Here are some screenshots:



I might be wrong but it does seem that the landscape segments with a higher number of painted textures are the ones that aren’t affected by the visibility tool.

May this be because my landscape’s materials are not set up efficiently?
I have ran into problems regarding painting my landscape before where I would get other strange results, but those problems seem to have fixed themselves when I reduced the ammount of textures on the material, which is not ideal since I’m trying to create a large landscape with a variety of sceneries that require a lot of different textures…

Here’s the post I made a while back just in case it might help:
