I am trying to add the "Burning Coals" material to my mesh. When I drag the material to the layer, it displays black on my mesh (and layer preview) but it shows the original color on the library.
You have posted in the Substance Designer forum but your screenshot appears to show Substance Painter so I'll move your post.
I don't have that material to hand, but it looks like it may be using an emmisive channel for the glow. Do you have an emmisive channel in your texture set settings? If not click the + symbol and add one.
