PC SDK Content Browser Bugsplat with use of Landscape Visibility Tool.

Reproducibility: Always

Summary: Creating a Landscape, using the Visibility tool and then viewing the thumbnail of the Landscape MIC in the content browser causes a Bugsplat.

Description:
If you create a landscape and apply one of the Landscape Materials (Blackforest or ZedLanding, etc), once you start painting, the Landscape will start creating instances of the MIC you use as a base for the Landscape.

When you use the visibility tool to hide areas of the Landscape - the tool works fine, however when you go to the Content Browser and scroll past the MICs it creates, the engine will bugsplat. The Launch.logs mentions issues of being unable to create Thumbnails.

The visibility tool is used in Zed Landing and Nightmare, so I was hoping we could use it as well - but this critical bug stops that from happening.

I've attached a map that will cause the issue - just click on the external packages in the Content Browser and scroll past it on the public build of the SDK to witness a crash:

I've also attached the Launch log:

I don't know - I'll have to ask around. Since it is a tool bug, rather than a game bug, it harms fewer people (but maybe devs too). Sculpting landscapes was always troublesome...

Edit >> This issue was added to the bug list, but it will probably get worked on until the after the holidays.

Ah yes, just in time for the mapping contest to be over

To add to this: If you use the Visibility tool and build the map, the landscape will bug out and revert to the default blue and white checkerboard in the published map.
Playing in the Editor is ok, playing with the map from the "Published" folder also works, playing the map uploaded to the Steam workshop does NOT work.

You can actually clip through the hidden parts of the landscape so this part seems to work, but it obviously looks horrible.

I found this out on monday - 2 weeks before the deadline of the mapping contest. There's no time left to do a proper workaround. Hundreds of hours wasted for a map that may never see a release because of this issue. I'm frustrated beyond words.
