Mayadolls have a different eye construction to say aiko or vicky, it's a 3 layer ball, idea is you set outer layer almost transparent, middle layer slight transparency, inner layer opaque. She'll import into studio with overly high specular strength like all poser content, select all the textures and crank the specular strength down to 70% before even attempting to tweak any of her texture settings. Although the latest version of MD is listed v3uv, that only applies to the skin surfaces, nothing else. Becarefull what mat presets you use, load textures by hand if you can. Then save as a MDV3UV specific studio mat preset.
