Hi folks

I would like to modify the pupil so it can be like a S letter. I am not satisfied with Photoshop result.



because the Iris doesn't really match with the S symbol.

So I tried to build a procedural texture in maya starting with a circular ramp



But as you see I miss also a point, as how to start the ramp with my S ?

In the end I would like to add noise texture with an implode factor matching the S as a start.



With this kind of effect :




Any help to achieve the desire effect ?

thanks

Fransua
