Skeletal mesh animation flickers when switching LODs

For some reason the current skeletal mesh animation resets with a nasty flicker when LODs switch in any direction. Happens both in game and in animation editor too.

What could be causing this? That didn’t happen in 4.12

Hey serioussam909,

I’m unable to reproduce this on my end. Can you expand on how you’re driving your animations on the skeletal mesh? Is it an AnimBP setup and could you expand on that? Are you using less bones on the LOD?

Attached an example project here.

To reproduce:

  1. Open Content/Blueprints/Characters/CharacterAnims.
  2. Change mesh to CivilianBody2
  3. Change Weapon Type to Rifle
  4. And then zoom in and out the viewport - you’ll see the ugly flicker.

Hey serioussam909,

I’m not seeing any flicker with your instructions. I see the shadows pop in and out, but that is expected. See Here:

There’s a possibility that this could be a performance issue. Can you send your dxdiag info?

Did you test the project using 4.13.1?

I updated the engine to 4.13.1 and that no longer happens for me as well. Looks like that the bug has been fixed.

This is the fix btw.

Yep, I was in 4.13.1. Didn’t catch that one in my search, good find.
