   I have a follow up question that fits this topic. I am also using Substance Designer and UE4, and while the look of the materials do seem on par between the two programs (especially after the UE4 sRGB uncheck mentioned above), I am a little suspicious of some of my settings, and want to make sure I am doing the right thing…

   Hi, You don't need to use a conversion node in the graph itself. If the inputs for the shader are images that are meant to be displayed, for example base color, then they are most likely in sRGB space so they need to be converted to linear space before computations are performed in linear space. In UE4, you need to set the…
