If you upload the texture using the properties tab under surface appeareance, an error will pop up;
“Unable to generate ‘Workspace.door_c.door_c.SurfaceAppearance’ due to some of the textures being unavailable. Change a TextureId property to retry”
The only solution i’ve found so far is by uploading the texture using bulk import (asset manager)
This is not really a big of a deal, but somewhat annoying to work with.
Edit: I used american flag as an example which did not work. I had to use bulk import to actually see the texture ID.
