Terrain Height Blending needs serious fixing

[itzchaser97]

There are two issues I am experiencing with Terrain Height Blending. One is a visual bug. The other is a literal game breaking issue.

Issue 1 - As you can see here. When Terrain Height blending is enabled, there are very noticeable black lines in the terrain textures at a medium distance. If you get very close to them, they are gone. If you get far away from them, they are gone. The brighter the landscape texture is, the more noticeable it is. I have tested this on some custom PBR Textures I have, as well as faultiers PBR Landscapes. It is barely noticable on faultiers landscapes. I'm assuming its because those landscape textures are darker. However, the issue is still there even when using those landscape textures. When I turn off terrain Height Blending, the black lines fade away after a few seconds. This leads me to the 2nd and more serious issue.

Issue 2 - After finding out that Terrain Height blending was causing this visual issue, I just decided to keep it off for the time being until it gets fixed. However, after disabling terrain Height Blending, within a couple minutes my screen completely freezes Frame indefinitely, yet i can still hear the audio of my character move around from my inputs. This is a very frustrating issue and I hope to see it fixed it the near future.

Hi, thanks for the report. I have seen these issues in a different form, but have no idea how to reproduce. It seems that most users don't get them at all.

I have seen the black lines before, but for me they appeared even with height blending or whole terrain parallax turned off. Weirdly they only appeared with Faultier's 4k textures and not 2k Sloppy vanilla textures.

As for the freeze, I and a few other users had this in some test builds, but it happened even with height blending turned on, and when I tried to catch it with a debugger attached, it never happened. After some changes to the code it never happened again.

I have some ideas on what might cause the freeze and will look into it, will try to check the black lines but they are very elusive.
