UE Crashes when Set Skeletal Mesh is called

Hi!

I’m experiencing some strange bug/crash in UE4.
It only happens, when i want to switch out a mesh with a “Set Skeletal Mesh” node using a button.
In Crash/Log report it only says “Fatal Error”.
Here is Crash log:

Also it seems that engine version doesn’t matter.

Hi ,

A few questions/requests:

  1. Please copy/paste Machine ID from Crash Reporter window here after this crash occurs, and be sure to Send report.
  2. Does this occur in a new project, or only your current project?
  3. Does this depend on a specific skeletal mesh, or will any reproduce crash?
  4. Can you give us some specific steps to follow that will reproduce this in a new project?
  5. You mention that engine version doesn’t seem to matter. Can you tell us which versions you’ve had this same crash occur, in same way?

Thanks!

Hi ,

  1. MachineId:A8F463BC455E7991CA6F82BFCA75908F
  2. It only occurs in my project.
  3. I have tried tried it with multiple skeletal mesh, but all of those were creating a crash.
  4. Used button “4” to call “Set Skeletal Mesh” node with a flip flop, so i can switch mesh with one button, but i will send project files in PM, so you can take a look into that.
  5. From 4.8 to 4.11 Preview versions get an instant crash when “Set Skeletal Mesh” node was called.

HI ,

I was able to reproduce this error and have entered a bug report, UE-26640, to be assessed by development staff. I noticed that if you switch skeletal meshes being called, editor will crash upon compiling blueprint as well, so it may be tied directly to skeletal meshes being used. I am entering a second bug report, UE-26642, to be assessed as well.

hello , has this issue been fixed as of yet?

i am having a similar issue

Hello guys, i was having this problem too.
If your character is doing any animation while he is changing mesh, let option: “Reinit Pose” unselected.
