Cloth APEX Change bug

Development Platform & Builds

I have a character with clothing imported from 3DS Max.
The Clothing is essentially a cloak.

Once the mesh is in I load in the APEX file into the skeleton and it works fine, some cutting but not the end of the world.
I decide to go back to the original 3DS Max file to alter the cloth behavior and save it as a new APX file.
When I load the new APX file into the skeleton cloak, it simply crashes.
Don’t know why

The only way to get it to work is to delete the character, reimport the character and load in the new APX file
Only then it’ll work, no idea why it happens, but I thought I should let someone know

No need to delete a whole character mesh. deleting only all APX file let you load another one without clash.

Hi pdcsky,

Can you please include the following information:

  • Call stack from the crash reporter windows
  • The Machine/Epic IDs that come up in that same window.
  • Logs from the crash in Project Folder > Saved > Logs (attach the text file here)
  • Does this happen in a blank project as well or only in your project?
  • If you have a test asset this could be helpful as well. I just tested this with a simple cloth asset and did not get a crash with 4.11.2. If you cannot provide a simple test asset please provide detailed steps to reproduce the issue along with steps you used with creating your asset and the settings changed.

Thank you!

Tim

Hi Tim ,
seems misunderstanding.
This clash is caused when another cloth(or the same cloth added double) applied to material,
not added to mesh.
to avoid that, must delete all .apxFile added to mesh before apply it.

My all clothes(simple cloth,flag,coat) cause this and
I set Owen’s tie cloth to his coat material. clashed

Ok, thank you!

I was able to see this with the Owen test asset but was never able to recreate with a new asset though. I’ve submitted UE-30039 for this to be investigated.
