Unlike a material made with Substance Designer, it is not possible to use the Substance Painter file directly. You must export the textures from Substance Painter to use them in Notch.
Your Painter project must also be created with the right presets.
In the Export panel option you need to choose the config “PBR MetalRough”, It is preferable to choose the TGA image format.
By default, the textures of Metallic and Roughness are in grey level. Notch uses RGB textures, you can change the export to RGB in the configuration menu.
In the Uber Material node you have to must place the textures in the right place.
Change metallic and roughness to 1.
The PBR materials need reflection to be complete. The easiest way is to use an Environment Map. Other reflection modes also work.
You can also link texture to the Uber Material node using the Video Loader node, and apply post fx to your textures.
