Hi again!
Found it!! you don´t have to edit or create the .ctmeye file as i thought.
Example for an eye-ball iris:
1.create your own eye-ball iris (with your favorite image editing software) and save it as a .tga file with alpha channel included, or in a different file.
2.apply a template eye to your character in CT7
3.push the eye editor button
4.select eye-ball iris
5.in the diffuse section push the import button and select your custom eye-ball iris from the folder where you previously saved it.
6.in the opacity section, select the alpha file if needed (if you have saved the alpha in a different file)
Done!!
