Duplicate function in Blueprint editor creates seemingly corrupt object

Development Programming & Scripting Blueprint

Repro steps:

  • Create a new Blueprint
  • Add a Static Mesh component
  • Set mesh to a valid one
  • Duplicate mesh (ctrl + W)

new object will be invisible and cannot be moved.

Copying and pasting works fine, expectation would be that duplicating should give same result.

Notes:

  • Duplicating static meshes in world viewport causes mesh to be set to an invalid name (some automatic renaming being erroneously applied), this may be related

Hi

I’m seeing something similar, but I want to make sure: If I duplicate Static Mesh component in Blueprint’s Components tab, it isn’t visible in Viewport. If I select duplicated component in Components tab, however, I can still move it in Viewport. Moving to another editor window, or closing and reopening this Blueprint, component is visible again.

static mesh component also appears in level viewport if I drag Blueprint into level. Selecting BP actor and duplicating a static mesh component in Details panel also seems to work without any issues for me. Can you confirm whether I’m following steps you take to see that?

Yes, model does reappear after I close and reopen window. I can actually move it, just widget doesn’t move, but after closing and reopening it’s moved by amount I moved it (as well as being visible).

As for bug in main editor window, it seems to be fine after an editor restart, I guess something got itself in a weird state but I can’t repro it now.

Hello

I was able to reproduce this issue on our end in engine version that you specified. However, after a bit more testing I found that this issue has been resolved on our internal build. This solution will be available in a later release of engine. Thank you for your time and information.

Make it a great day
