If the holes comes only in render, it could be a problem of normals or UVs texture.
-normals problem :
select your ears, and find the normal menu (depend of what version of maya you use) edit polygon or menu normals...
choose "set to face"
-UVs tex problem :
verify you v correct UVs, not someting weird in the uv editor, check with a other texture.
other thing, verify you v got realy a texture applied, sometime it happen...
delete history (who know ? ![]()
cheers
