In my case, Sirome(render queue) sits at 2900, so I bump Hitomi(render queue) to 2901–2902.The Fix: Select the head mesh and go to the Render Queue property. Ensure that the iris (cf_m_hitomi_00) has a strictly higher number than the eye whites (cf_m_sirome_00). A standard stable setup is setting cf_m_sirome_00 to 3000 and cf_m_hitomi_00 to 3001 (or 3002).
Thank you gemini. Aka go to the material editor and look for those two.
Leaving it here in case someone got problems with the stupid eye. Likely the client defaulted the card's setting or the author intentionally mess it up.
At 2903, it starts overlapping the upper eyelashes.
