Hello.
I recently encountered some editor crashes when trying to open a level. It took a while to figure out what the issue was, I assumed that some of my materials or something from the marketplace was somehow incompatible with the M1 architecture. That seemed strange, and when looking through the error output I noticed it mentioned ApplyLandscapeCircleHeightPatch_out. I removed all landscape patches from my actors in the scene and bam, the level will load.
To ensure that this wasn’t still an issue with my project, I reproduced on a brand new blank project. Here are the steps:
- Create a new blank game project from the editor launch screen (this open the open-world template upon startup. if not, create a new landscape in the level first)
- Enable the “Landscape Patches” plugin and restart editor
- Create a new actor
- Add the “Landscape Circle Height Patch” component to the actor, compile/save
- Attempt to place the new actor in the scene
- Observe the error
I understand that this feature is experimental, so some issues should be expected. I have not encountered this problem on my PC.
I’ve already submitted this as a bug report, but also was wondering if anyone else has had this issue/could reproduce it to further rule out environment issues.
I wasn’t able to find anything regarding this by googling parts of the error output, so hopefully if someone else has this problem they’ll be able to find this post.
Here is the full error log:
