B is for Ben: 3D model texturing by Rok Andic

Here is the final textured model of Ben. If you look at the environment concepts post you can see that I initially had blue details in mind for his suite. I really liked that idea of contrast, but once I put it in 3d he just looked odd. He looked more like an aquanaut rather than an astronaut. So I started playing with warmer colors and decided for a more orange/brown colors for the suit details. It instantly looked better and his space suit didn’t look like it belonged underwater.

I also added some model details before I started texturing. I decided to add a small computer/button panel with straps on his chest. It looked a bit empty when I made the final sculpt so I added it just before going into texture. I was going back and forth with small gadgets and what would work and what not and in the end decided to stick with a small button panel.

Workflow

I did all the texturing in Substance Painter. For initial fabric pattern I used Substance Designer and then added all the grit and dirt details in Substance Painter. I really like how patterns are easy to create in Designer and used as a base in Painter where I can add all the details. I am also one of those who uses a lot of layers. So whenever I add some scratching, tear or wear I always do everything on a separate layers so I can come back and remove every single effect if I need to. It also means that sometimes I just get lost in all those layers :)

When everything was painted I exported EXR UDIM’s to Houdini where I connected everything together to create the final look you can see below.

B is for Ben: Ben base sculpt by Rok Andic

Finally started working on our hero character sculpt. I decided to do it a bit differently than the way I worked on “A is for Al….”.  On later I did the final sculpt in Zbrush, retopology in Houdini and then reprojected the details back on the retopologized model. The problem with that is that some details don’t necessarily stay the same when reprojected. This is the reason I decided to do a base mesh without high detail first and do retopology on this mesh. Once that is done I will work on the details on this model. This will help me speed up the work on the details of the model by working on them only once.

Apart from that, my workflow for creating the character is pretty straightforward. I start with base shapes like spheres and boxes and shape them to best  represent the character. These are merged together into shape via Zbrush Dynamesh. Then I simply work on the details.

Notice that I leave certain things unsculpted, like the mouth and inner parts of eyelids. I will do this in Houdini when I will be making the retopology of the model. I simply find it faster this way to work on interior shapes there, also it is easier to work on the base sculpt for me if there is no interior shapes to worry about.

Next stage - retopology in Houdini.
