Bone size too small to create physics asset

I have been trying to create a physics asset with this skeletal mesh, but of course the bones are too small.

I have tried importing it after setting the Blender unit size to 0.01, and scaling the mesh 100x. However, if I apply transforms then it will be huge in UE4, which is difficult to work with inside of the physics editor. If I don’t I have the same problem.

Hello there @BluAstronaut!

Importing and exporting between UE and Blender has it’s own array of conflicts. The difference in the unit size might be too large, try adjusting to lower valuers (0.1 and 10x). Also, please make sure of the following in Blender before sending back the asset to UE:

  • Apply any and all active transforms
  • Apply Scalings set to “FBX Units Scale”
  • Forward set to “-Y Forward”
  • Up set to “Z Up”
  • Apply Unit, Use Space Transform, and Apply Transform, all set to “Enabled”

If regular export still gives you issues, test using Send2UE. Alternatively, you can try a different transfer addon, like the one below:
