Black dots on meshes/textures

I am currently working in UE5.0.3 and used the VR template as a start. I created a new level and started modelling, however I currently have a problem with black dots on meshes and the landscape to which I cannot seem to find a solution.


The dots are also flickering while moving so it’s really annoying. Opening the mesh itself doesn’t show the artefacts.
The meshes aren’t nanite meshes and I think Lumen/raytracing is disabled in the VR template by default (it is locked in the settings so i can’t change it either).

Does anyone have an idea what might cause this?

Welcome back VRDongen. Thank you for posting.

Since you started modeling, would it be possible you may have accidentally edited a few engine meshes? If so, you may be able to correct this by clicking “Verify” next to your engine’s launch button in the launcher. It may take a while to verify.

I hope this helps.

Hi Polite_Muon,

Thank you for responding, I have verified the installation but the issue persists.
I don’t think this is the issue because it happens on multiple meshes (not all though).
It happens on the landscape, a custom modelled mesh using the UE5 modelling tools and on meshes imported directly from Bridge:

One of the other meshes I modelled doesn’t have this issue though.

Maybe it is an issue with the textures/shaders? I’ve got Virtual Textures enabled (disabling it doesn’t solve it though).
The mesh that doesn’t have this issue is a mesh using vertex painting so maybe this is why it does not have the issue.

I have the same problem.,

problem solved,you just need to verify the version of the engine
