Yes, that's Apollo. I just plugged the color and bump into a PhysicalSurface node and set the relevant values to whatever I had used in Antonia 1.3. The final shader looks like in the image below. The cascade of Spots and Blender nodes at the top was just copied over from Apollo's original material. I didn't use the displacement maps because they were too noisy and had too much striation on the pectorals, as if the poor guy was constantly flexing his chest. It might be nice to edit out the bad parts and use the displacement map for the nice veins, but I'm assuming the license would then not allow one to redistribute such a modified map.
