animagic is right: if you're displaying a toon character, it should have toon hair (smooth shapes)!
But fundamentally, iClone is good at Toon Shading... as long as you turn off the Toon Shader and don't trust it again!
(A) To render a flat, cel-shaded character:
Your first step is always to thoroughly toon the character textures:
- simplify the markings of features
- flatten the colors
- crank up high Self-Illumination.
You'll get perfectly flat cel-shading using the _DH Default_CC Atmosphere (same as in Character Creator):
- Turn off all lights.
- Use yellow or white Ambient light.
- Render the cel-shade video.
(B) If you want highlights on your character, render another pass using the the _DH Default_IC Atmosphere:
- Ambient light: black.
- Key light: white, multiplier 20x.
- Side, Back, and Floor Shadow light set to black, don't bother with the multiplier.
- In the Content/Effects pane, apply the Color Adjust Effect 3 times. They will appear in the Visual Tab under the Effects icon. Use max gray style and tweak the output to get as close to pure black shade with the white highlights as possible.
- Render the grayscale video.
(C) To composite the flat character with sharp celshaded shade:
Using a powerful free editor like VSDC, load the (A) video in the first track.
Load the (B) track above (A):
- Increase the contrast to reduce any grayscale to simple black on white.
- Change the Blend mode (for example, Addition).
- Reduce the track Opacity until the shade/highlight colors look right.
- Render the composite video (C).
