Scaling of child blueprints applied incorrectly in editor

Since upgrading to 4.9 we’ve experienced a problem with scaling child blueprints.

It seems to be applied twice in blueprint viewport and in editor; but in play (either PIE or cooked/packaged game) it is correct.

This makes it difficult to visually verify asset tweaks.

Steps to reproduce:

  1. create Cube static mesh, and a blueprint for it
  2. create Sphere static mesh, and a blueprint for it.
  3. Mark both meshes as ‘movable’ in both blueprints.
  4. In Cube blueprint, add Sphere blueprint as a child, and scale it.

When placed in the level or in viewport, this spehere is scaled two times, but in play it is scaled as expected.

Hello xulture,

I was able to reproduce this issue on our end. I have written up a report ( UE-20915) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day
