Is is possible to make in Panda3D “out of box” shape (mesh) with shine metallic material, like it is possible in ThreeJS, shown here:
https://threejs.org/examples/webgl_materials_displacementmap.html
Try especially at “roughness” about 0.1, it looks just like polished metal, almost mirror.
Not quite “out of the box”, but with either the simplepbr or complexpbr packages I imagine that it could be done.
In short, Panda doesn’t have support for PBR materials–the sort of materials that you seem to be using, that include metallicity, roughness, etc.–“out of the box”.
For such materials, an add-on is called for–with the two that I’m aware of being the two to which I linked above.
Making a fully shiny metal is easy, out of the box. You just need to apply an environment map.

I recommend simplepbr for anything more than that.
