Fixing Eye Textures on Brawl Characters

[xbeton0l]

Hi there. I've completely finished a custom model for Sheik, however whenever I test the model in game the eyes show up extremely glitchy and pixellated. I don't know what to do to fix the eyes. Is there a specific workflow for making sure all of the textures, shaders and other parameters needed for the eyes are correct?

I've literally searched Google for the past 4 hours and have found nothing but indirect results. Please help!!!
