in order for the larger iris mats to only cover the "iris" material,you will have to manually remove it from the "eyewhite" material of the eye. example Thorne and Sarsa eyes when they make their irises they extend the iris onto the eyewhite material,therefore making it look bigger,morphs are not going to change this. change the eyewhite material to one of the mats you have with a smaller iris. hope that helps :0) -3dz
