Here you will find some simple tutorials, to turn a cartoon style rendering into a proper cartoon via controlling the palette. Not to boast but some solutions are a matter of instinct gained by experience.

But with DazStudio it could be made easier by removing all lights and textures, (including the trasparency maps and bump maps), give well defined colors (like the eight combinations FF0000, 00FF00, FFFF00 ) to the surfaces, and then create a palette with a ramp for each color in the model.

By example the ramp for FF0000 (Bright red) should be like

CC0000

990000

660000

330000

1A0000 

 and so on, as you can see in the first image

when you convert that image and force in such palette, the colors won't get mixed, if you removed all textures and lights, and you can modify the palette ramp by ramp, as you can see in the second image.

If you download DazStudio you might have to learn about how materials (in that program ar called "surfaces" work)

Those are the assault classes i already rendered, the dude is the second from the left.

Every class will have their own bodytypes.

Altough they'll fall in the logic tall/normal/short muscular/fit/sporty/thin/fat for both genders, every class will have theyr own bodytypes. Chances of 2 monsters being identical (with different uniforms and movesets)are very slim. 

Thank you very much, i'll probably need those in future.
