I started my process of building my character in ZBrush by looking at the tutorials provided by Lynda.com.
Because I've never used this software before, the tutorials were very useful to familiarise me with the basics of ZBrush. I started with the ZBrush 2018 Essential Training to get around how to use the brushes and the general idea of the interface.
I moved on to the Sculpting a Creature with ZBrush and Photoshop to start my character. This tutorial was not very helpful to me given the design of my character (a human female body) but it gave me a good idea on how to make a base for sculpting, that being using armatures.
After many failed attempts I came to the conclusion that the armature won't work for me. Zbrush would constantly freeze and crash while assembling the armature and it became too stressful.
I discarded that idea and went on YouTube to look up more tutorials on how to build a female human body. After some research I decided to use my Maya knowledge to build my base. This turned out to work very well in my advantage because I build my body-base quite quickly.
I also made the base of her robo-arms in Maya as well and attached them to her body since it was easier for me to build the arms and the body separately.
Before I started sculpting the body, I made some tests on the arms to see how I would sculpt them since in my concept sketches I didn't have the necessary details of the arms, just their general shape.
I took the base I build in Maya into ZBrush and started working on the details
I mainly used the Damian, ClayBuildup and Flaten brushes to figure out the shape of the fingers and palms.
I got a good idea about how I wanted them to look like and then moved on to sculpting the body.
This was another failed attempt but what I learned from this one was that I should leave the head at the end to sculpt it, after I was done with the rest of the body and clothes.
I also couldn't figure out how to cut parts of the tool. My idea was that to cut the "derpy" hands and attach the arms that sculpted separately but it didn't work.
So I went back in Maya and attached the base-arms to the base-body and restarted my sculpting process in ZBrush.
Sculpting the body itself was not very hard since I have a basic knowledge of anatomy.
I used a reference image showing me the anatomy of a female body to help me figure out how certain parts of the body should look like in 3D such as the back, the shoulder and the collarbone.
For this part I mainly used the ClayBuildup brush and smoothed everything at the end.
