Face Tool : How to see/load those edge lines in ZBrush?

Hey guys,
I’m following this tutorial which got everything I want to do but at ligthning speed without showing how to do a lot of the things we’re seeing on screen… which quite defeat the whole purpose of a tutorial…

So I really need your help to learn how to get those edge lines around the eyes in ZBrush, and if possible a real step by step description/guide about what’s going on when his refining those eyes.

In fact I used a scan I made and projected it like in the first part of the video, but the eyes, and btw the mouth too, are deformed like if they’re starting way too much from the inside. It’s like the skin which should be at the limit of the eye was in fact pulled in the eyeball socket if it make sens… Same for the mouth …
Hence why I’d really like to learn how to fix this by viewing those edge lines as a more precise alternative to polygroups.

Ok I found it, I had to click in the Face Tool panel on Diffuse then Range which then shows the topological lines…

Now I’m still faced with the challenged to pull those lines from the inside of the eyes to the place where they should be, and it’s really not easy to bot destroy every thing up there… I so wish there was a tool to make those geometry lines like sliding on top of the mesh, but that’s not how things works, or I just don’t know how to fix this smoothly enough… if someone as some tips to help me fix this I’m all ear!!
