I have a model with one material. I used some basic properties and some shader nodes with it. When I create a FBX file and import it into Unity, the model appears correctly, but its material is empty. I can see the material, but it doesn’t have its data with it. Why is this happening? What am I doing wrong?

every 3D app has it’s own material and shader system; there are some “trials” to solve/unify this like :
But mostly one has to double check which format can do what. You might have look at for example this:
or follow some “advice” on any tutorial like so:
and/or share your setup by some screenshot or even blend file.
