Wrong face orientations on some displacements about plumber HOT 4 CLOSED

It seems that the face orientation of the mesh is wrong.

I assume you have enabled backface culling, in which case the material would appear invisible from one side. Can you check if the material is visible from the other side?

Also found another issue with importing some of the materials there, but that is probably unrelated.

will check
btw did not tick allow backface culling in import settings.
Yup, material is visible on the other side.

Looks like there is a bug in the backface culling setting too, it is always used regardless of what the user selects.

I will see if I can find the problem with the incorrect face orientation.

This should be fixed now.
