For this next step I made a bit more use of 3ds Max. It is a lot easier to do hard surface modelling in Max than ZBrush, and I recommend using Polyboost if you're box modelling in Max! I imported a lower-res version of the model from ZBrush to use it as reference. I had to go with a different gas mask design than the one that I initially planned because the full head model was harder to bend and place onto the chest. The straps were very easy to make; I used the shell modifier to give them thickness at the ends (Fig.07).
When detailing in ZBrush I was trying to give a suggestion of the objects inside the bag, and so I made sure I took these into account when I was creating the folds (Fig.08).
I wanted to give a weapon to the character as well, to make it more interesting and give him a bit of a back-story (Fig.09). So he became a medic with a gloomy past, going on the rampage with a flamethrower! Gas masks also go hand in hand with flame throwers! I added some damage to the tubes and made some quick details on the hose (Fig.10).
I assembled everything together in ZBrush. I created layers for the objects that I knew I would modify, in the case I needed to go back to the standard pose. I then used Transpose Master to pose the model. Some modelling was necessary to correct the parts that didn't deform properly, and I also had to redo the folds that were not flowing in the right direction, according to the new pose (Fig.11 - 12).
The rendering was done in V-Ray. I decided to take the entire model into Max, but this was a problem for me because I only had 2G of ram. A workaround was to split the model into different files, ticked "display as a box" option before saving, and imported them as xrefs into the main scene.
The lighting setup was very simple and consisted of just two area lights (Fig.13).
With the final image I went for a simple and clean look. I wanted the details to be easy to read so that the work that had been done in ZBrush would not be wasted (Fig.14)!
