Editor crashing when setting Spline mesh with Landscape loaded

Steps:

  1. Create a new tiled landscape using world composition
  2. Load the tiles
  3. In landscape edit mode, select spline edit
  4. Create some splines using Ctrl + Click
  5. Ctrl + A to select all mountains icons
  6. Set the mesh in control panel
  7. Voila it crashes!

Thanks, I was able to reproduce the issue easily with the latest 4.8 code. I opened ticket UE-16397 for the issue and we’ll try to get the fix in for 4.8 release.

Thank you :slight_smile: BTW is it normal that once I added some splines, when I hit play or press G the splines disappear?

If you haven’t assigned a mesh, yes. If you want to use the same mesh that’s used in the editor, you can copy /Engine/EditorLandscapeResources/SplineEditorMesh

Thanks. I’d like to add to my bug report it’s also crashing when moving a spline

Thanks for the report, both issues should be fixed for 4.8 release.

Note, the crash is related to the new bPlaceSplineMeshesInStreamingLevels option on splines. It is broken on control points (it works perfectly on segment meshes) in 4.8 preview. You can disable that in the mean time to avoid the crash. Save often!
