Flickering Static Mesh

[osiris231]

Some of my static meshes flicker.
My level design is very modular so I have many instances of the same static meshes with the same materials yet only a varied few are flickering.

If it makes any difference the meshes are positioned in a way similar to that of a picture in a picture frame, you don't see the bounding vertices, only the face between them, the vertices are obscured by a framing mesh.
The offending meshes are in exactly the same setup as those not flickering however in a different position/rotation.

Any ideas?

Using any Translucent materials or Movers / Interpactors?

[osiris231]

No translucency not an InterpActor, completely stationary

OK, so the usual suspects can be eliminated then....... What about lighting: dynamic or static? Flickering happens in editor (real-time icon on) or only in game?

Also, specify the materials you're using and whether this problem happens if no materials are applied to the meshes (i.e. default blue / white grey look)...

hmm, interesting. When I change to the default material the flickering goes away.
Static lighting, dynamic shadows.
I'm using a custom opaque phong material with a reflection cube and WorldPositionOffset with vector painting

Edit: What I don't get is that it only happens on some instances and also sometimes it stops flickering depending on the camera angle.

Also happens in game and in editor

WorldPositionOffset with vector painting affected by the camera angle, rotation, and / or distance?... Makes sense I suppose, although I'd usually associate that with BumpOffset ... Anyway, do another 'idiot' check and substitute the material with a different opaque phong and re-confirm the problem isn't related to mesh design or something different...

I had the flickering static mesh problem after changing settings in my dominantDirectionalLight. I deleted the light and began it again, watching each setting change I made.
