Metal Preset is a material for Substance Painter that has 39 PBR accurate values for a number of metals. Values were sampled from scanned data and other sources such as Quixel, Allegorithmic, Unity and Dontnod's PBR value charts.
To install the files, simply drag and drop them into the shelf in Substance Painter. This will open the 'Import Resources' dialog. On the boxes to the far right change the category to 'basematerial' and in the drop down near the bottom change 'Import your resources to:' shelf 'shelf.''
To use Metal Preset drag it from the material shelf into the layer stack. For most applications simply change the preset with the drop down menu under 'Metal Preset.'
For more advanced options select the 'Custom' option under the drop down and activate the toggles to fine tune the material's values.
The Metal Preset material only contains base values. To add more detail to the overall material I like to add a grunge texture to the roughness channel, set it to overlay and lower the opacity.
