Thought I would share one of the models I completed during the development of ZBrush 2019. This model was done with the new Spotlight SnapShot3D mode.
I also designed and modeled this ship using the Preview>Flat Shadows mode with a Flat Shade Material. I knew that I wanted a final toon look with an outline. It was great to just work with the model in real-time as I built with out having to worry about it looking different when I rendered.
I experimented with a couple of materials but I ended up using FlatShade01.
Here is a project with all 5 materials and with the settings I used to render all of these images. Feel free to download and experiment.
FlatShade01
FlatShade02
FlatShade03
FlatShade04
FlatShade05
Here is what all of the materials look like on a sphere in the attached project.
Enjoy
