Okay, I’ve figured out what was causing the crashes. Changing a procedural splineMesh blueprint to being a closed loop causes maps saved before that change was made to crash on load
To reproduce:
- Create a procedural splineMesh blueprint (I used this method): UE4 Tutorial: Add spline-meshes procedurally - YouTube
- Create a map (I’ll call it map1) and add that procedural splineMesh blueprint in.
- Save that map
- Create a new map (I’ll call it map2) and add that procedural splineMesh blueprint in.
- Edit the procedural splineMesh blueprint object to have a closed loop spline (note that map2 continues to work just fine, and can be opened and closed without issue)
- Save everything
- Open map1 - the editor will crash.
Sorry if this is convoluted - there’s probably a simpler way to reproduce this, but this is what works for me.
Old Post: 4.7.6 Project crashes on map open
My 4.7.6 project crashes (to the crash reporter) when I open my map.
The project worked fine until recently. Last time I was using the editor, one small test map (not the map in question) refused to save due to not being able to locate a dependency (or something similar - can’t quite remember). I quit without saving that map, since I couldn’t get the error to resolve. Next time I went to open the editor, it would crash on startup. Other posts advised to change the default map in the DefaultEngine.ini to “/Engine/Maps/Templates/Template_Default”. This change allowed me to open the engine, but if I attempt to open any other map (not the test map) a crash occurs. I can create new maps with all the same content, but not open any of the old ones.
Project details:
- Fairly small project
- Only blueprints, no c++
- Using the launcher version of the editor, not github.
- OSX 10.10.1
