is there a format that will work better with Max / Arnold than others? I exported my textures using the 'Arnold 5' preset in Substance Painter, so I don't really understand why that wouldn't work. Michiel, you asked what format and bit depth my texture was. To sum up, I have tried to export from Substance Painter with different presets (Arnold 5, PBR MetalRough), exporting to a different format and bitrate, tried overriding the gamma at 1.0 at import, connecting a range shader between the texture map and the specular roughness in Max - as well as changing the material type to a Physical Material.

It's very demotivating to work on rendering this way, so I'm determined to get to the bottom of this. As you can see, the substance render has 'texture' on the materials, but the Maya render is just a solid color I set the BaseColor file into 'Color', the Metalness file into 'Metalness' and set 'Alpha is Luminance'. I have had some difficulty with my roughness maps in the past, generally they have been way too glossy and not really showing the same contrast or detail as in Substance Painter or Sketchfab. This is the Maya render using Arnold, and this is the render in Substance Painter using iRay. This comprehensive workshop by Sefki Ibrahim demonstrates how. I included a snapshot of the material as well. Whether its in movies, TV shows, music videos, or video games, digital humans are everywhere. I tried to connect a range shader between the texture and the specular rougness, and made sure to import the map with gamma at 1.0.
