I am recreating an ancient settlement with Blender, and to make my life easier, I modeled several types of ceramic vases with procedural materials on a separate file, which I appended (not linked, since I need them to have different materials) to my main file both via the asset browser and File > Append.
The problem is that these appended objects have very bad quality. It seems the edges are "jittery" and when I switch to render view, I can see all the edges, as if the faces were floating and detached from each other. This doesn't happen in their original file, as seen in the image above. This happens with all the objects and all materials (including the default white) in the main file.
Is there any way to fix this?
EDIT: Here's a link to a folder with both files. If everything is correct the ceramic objects should be in the asset browser of the main file (tfm_send) already, but if they aren't, appending any of the objects through File > Append gave me the same results.
