All meshes have become transparent, materials not displaying

I need help with UE5, all of the mesh objects have become transparent, almost like the geometry normals have been inverted inside out, but it is for every mesh in the scene, textures are also not properly displaying, any help is appreciated

Hi Josiah,

I vaguely recall someone with a similar issue. Resetting the UI worked for them.

To reset the layout:

Window → Load Layout → Default Editor Layout

Welcome to the Forums, let us know if that helps!

Hi thanks for the response, I have tried this, it resets the UI but does not change the problems with the meshes

If you create a new project, do you still see this issue?

I just checked an old project and created a new project and it seems to be only the one project that has the issue

Ok, try this: Make a backup of your project (just in case) and delete YourProjectsDirectory/Config/DefaultEngine.ini (and if that doesn’t work try deleting the entire config folder) - That file/folder will be regenerated the next time you launch the project.

Thank you very much for your help and time, it was indeed something in the DefaultEngine.ini file, it now works.

This is how it should look:

The problem is the Near Clip Plane setting in the Project Settings.
When you set it to 0 it will cause this issue.
Set it to a value like 0.01 so you could still adjust camera’s near clipping plane and not break everything and not reset all your project settings.
