I’m on 4.6. I’m trying to create a blueprint camera that uses a spline to travel along. 3 times so far (in about 8 hours of work), the spline points reset to the default 2 points. I don’t have a repro case yet, but it’s super annoying so I wanted to report it.
Edit: Assets Uploaded.
Try adding it to a .zip archive, you should be able to upload it then.
Sweet. Thanks!
Hi Charlie,
I got your asset working in a test project but so far I haven’t been able to reproduce what you are seeing. Do you remember what you were doing each time before the error occurred?
I was building the initial event graph, construction graph, function graph and recompiling a lot. Every once in a while when I selected the camera in my level, the nodes reset back to 2. I’ll be getting back to this issue tonight.
Hi Charlie,
Have you had time to look into this issue further?
I’ve been working off and on with the splines since the issue appeared and it hasn’t yet occurred. You can probably resolve this issue, if it pops back up, I’ll post a comment.
Just experienced this. I was editing the spline BP to move another BP actor along it’s spline path. Happened 3 times. Went to the level editor and the spline had reset
Hi DG Gage,
We’ve been trying to get a reliable repro on this. If you can successfully reproduce it in a new project, could you post your repro steps here. As exact as you can be.
When I tried to repro this issue myself, I was unsuccessful. How strange.
What I was doing was setting up a timeline in the spline BP to move an actor along its path. Before, on a few occasions, when I switched from scripting in the BP to the level editor, the spline would be the default 2 points.
But… tried again… and everything worked just fine.
I will definitely inform you if it happens again, and try to produce a repro to target the cause of the “bug”… if it is indeed on the engine end.
I noticed that it happens when you you get a blueprint compile error while editing your class with splines. Also it produces one “deleted actor” on scene graph (disappears on next save) and a record about “removed actor” in logs. I’m on latest 4.8.3 and still have this bug
Same issue still, i’m on 4.9.1
Seems to happen when compiling a blueprint with spline with error, as mentioned above.
Hi Olle3000,
Thanks for the info. What seems to be happening is when a blueprint receives an error message, it is losing the data cache. When this happens the spline data is lost and it resets. It’s been logged as JIRA UE-20385 in our system and we are investigating the issue further.
Cheers,
TJ
Okay thank you, would be great if you could fix it
