[4.9] Renaming component resets values

Hi there,

(this is a follow up toanswers.unrealengine.com/questions/302535/49-reset-blueprint-to-default-values-doesnt-work.html)

When renaming a component of a blueprint, the values are reset to default.


  • Create new test project
  • Create Blueprint actor class, add a static mesh component ‘SM_Mesh’, leave the default mesh (white cube)

  • Place instance of actor in level

  • Configure the property SM_Mesh in the selected instance (change mesh to a sphere, change also the material)

  • Now open the Blueprint again, change the name of ‘SM_Mesh’ to ‘SM_Mesh_renamed’.

  • Instead of just renaming the component, all values of the instance are reset to default

Hi ,

I deleted my original post as it was actually meant for the bug report you have linked above. I was also able to reproduce this and have entered a bug report, UE-21109, to be assessed by the development staff.

Thank you.

Any news on this bug UE-21109 ?

Hi ,

This bug is still under assessment by the development staff. Unfortunately, I do not have a timeframe of when a fix will be implemented.
