Topology Correction, Step 2 (Rigging and Topology)

So you got 2 different meshes saved out, if you just decided to load ZBrush and its fresh, you can always go under LOAD TOOL and load them out.

Now first off, Open the file I told you to name ''C4'' and set it on a Subdivision Level that has near 1 000 000 polys, once you get that done, the next step is to click once again on the ZSphere Tool, just like in the beginning of the tutorial.

You should have a ZSphere in the middle of you workspace now, the next step is to RIG the C4 mesh onto the ZSphere, here is where you can find it and how to do it;

So first you click on RIGGING, then when the Tool opens you should see a option named SELECT MESH, if you click on that command a bigger window should open, and under Quick Pick you should see the C4 mesh, select it.

Now that you did that you should be able to see something like this;

What this allows us to do is see the C4 mesh and draw the lines on top of it so they can follow the shape, but we saved out the C4_Del file too so it can save us some time, now, what that will do is simple, it will draw the lines we deem good on this mesh projection, to do so you need to go under TOPOLOGY TOOL and click on the option SELECT TOPO, after that a similar window as the one in RIGGING will pop up, and all we have to do is select C4_Del. as seen here;

Once C4_Del is selected, next thing you have to do is click on EDIT TOPOLOGY, and everything should look more or less this way;

Why I'm saying ''more or less'' is the fact that your transparency might be a bit different, and this is one of the things noone will explain you what to do with, everyone thinks you have everything fine and dandy... but I spent hours first time I was playing with the topology trying to figure out what was wrong with my ZBrush until I stumbled upon a Post that gave me a good idea, and I'm gonna share it with you in case you are as lucky as me!

There is a option box in top bit of your screen named PREFERENCES if you click on it you will see a dropdown window with loads of options, you are only interested in DRAW for now, once you open it a few options should pop;

Alright now you can see few options here, first off;
TRANSPARENCY DEPTH; what this controls is the depth of your transparency, keep in mind that your model up till now is hollow and doesn't have a depth to it, your skin on the mesh doesn't have a thickness, so this is useless for you at this time.
FRONT and BACK OPACITY; now here is where the moneys at, changing these two will shift the opacity until you find your desired option of view, this varies from person to person and to each its own.

Here is where you can find them;

This concludes the second step in the Topology correction process.
