FABRIK Crash

berguina · April 21, 2015, 2:20pm

I’ve noticed a strange behavior when using FABRIK node

. The debug lines are displayed even in game

and after a while the game crashes with this log:

Windows 7 / 64bit Unreal 4.7.6 binary version. [dmp file here][3]

Just for clarification: it crashes only if debug draw is checked on the FABRIK node. But the debug draw appearing in game is incorrect: it always appears around origin. Also, debug draw never disappears nor in game nor in preview in editor.

Hey berguina,

How long are you letting the editor run before it crashes?

Hi ,

It crashes when you play in editor, pretty fast, maybe one-two minutes.

anonymous_user_280dd372 · May 6, 2015, 1:50pm

Hmm, I haven’t been able to reproduce the crash here using just a third person template. Do you think there could be something else in your project that isn’t playing well with debug draw?

If we can’t repro here, I might ask if you could send along your project. If you think that’d be ok, you can upload it and PM me the link.

seams turning on debug draw in Fabrik causes it to crash when launching the game. just fyi

anonymous_user_280dd372 · June 2, 2016, 9:55pm

Hey Spectral Ink,

After taking another crack at this, I got the crash immediately in newer builds. I entered UE-31585.
