Flicker between meshes

Hello, may I know the cause of these flickers? I am sure that there are no overlapping meshes and it only occurs in PIE, not in editor viewport. What should I do to fix this? Thank you.

What are these? Is it the editor cube, or your own meshes? If the second, are some parts of the mesh open?

editor cube. I tried making it emissive in an unlit map it looks perfectly snapped. I suspect the lighting.

What sort of lighting do you have? ( static or dynamic )

Have you turned on anti aliasing?

I’m using default lighting not sure how to check if static or dynamic but it says mobility: stationary and no anti-aliasing.

Ok, well if it doesn’t matter ( which it wont unless your a static lighting nut ), just switch directional to moveable and skylight to stationary. What happens then?

I tried and here’s what’s happening

Ok, now I’m wondering about the material. Is it just 50% grey or…?

Here’s my material.

Ok, starting to run out of stuff here. A few more ideas:

  1. Have you tweak ANYTHING in project settings? Does this happen on a new default project?

  2. Have you tried visualizing out of bounds pixels?:

  1. Make sure you have the latest drivers for your card.

Is it for a mobile game? If so, there might be settings in the material that are not compatible with the mobile renderer. It’d require searching on the site and/or elsewhere to see how to set up mobile game materials correctly.

For the Out Of Bounds Pixels check, here’s a link to how to use it:
