Oh ok, but why if I export this mesh and bones from MAYA physics assets created perfect in UE4?

here Gif with default settings

Here pic with default settings export

Always glad to help!

U dont need to set video, just open new blend file and go to clip editor and press E choose "track markers"
Yes it happens in factory settings and only pie menu addon.
No. I dont need any markers in scene.
p.s. attach video file with crash in first masage.

guys, one question, Steam version 2.7.4 000dfc0 ?

Np, thanks for the quick replys.

oh lol, thats because by double clicking blender open 2.73v. In v 2.73 dont crush but in 2.74 000dfc0 always crash.
p.s. In latest build (blender-2.74-94d80c8) don't crash

And ur right u can delete or hide object then choose action and it will crash. I find one more interesting thing! If u open blend file by double clicking on it it will not crash, but if u open it in splash window or file->open it always 100% crash! Now rec vids for u

Ok, I record video of it, and share blend file
