Hello, I’m trying to use the Visibility tool to create holes in the terrain, however it hangs and crashes the editor as soon as I click on the landscape with the Visibility brush active. I’ve tried it in a new scene on flat landscape and it seems to be fine, however I can’t think of anything that could break it in my scene, it’s just a landscape that I have imported over from World Machine.
After further testing, it does seem to work occasionally on some parts of the landscape, however as soon as I try to do it in a specific area where I want the hole to be, which is a little more slope-y, it crashes.
Here is the crash report:
