Landscape visibility tool not working

Using version 4.10.4

When using the landscape visibility tool I can only paint the visibility on certain parts of my landscape. As you can see in the pictures is seems to be limited to random blocks.

The actual area where I need to paint is near where the cursor is in this image, yet nothing happens when I paint there, holding ctrl or not. (The orange bits show where the tool is actually working)

Here is another shot showing a bit more of the landscape, I cant think of any reason why those particular blocks wont allow being painted on with the visibility tool

Update:
It appears that the collision for the terrain is still being painted with the visibility tool correctly even though parts are still visible, so there are parts of the terrain that the player can fall through even though it is still visible.

Hi squinty,

I have not been able to reproduce this on my end. Can you show me a screenshot of your material setup?

Here are the shots of my material.
This problem seems to have fixed itself, I moved pretty much all of the scene to a new streaming level, and its now working normally, though I cannot be sure that it was moving the level that actually fixed the problem, but you can mark this solved anyway.

Hi Squinty,

I’m happy to hear you are no longer experiencing this issue. I am marking this as answered for tracking purposes. If you experience this error again, please comment with updated information and I’ll be happy to take another look.
