Let's use Clip Studio Paint's functions to paint skin
Introduction
Clip Studio Paint has a variety of functions.
This time, let's use them to paint skin.
Even functions that don't seem related to painting can be useful depending on how you use them.
We've also prepared a video, so if you understand Japanese, please take a look.
Material Utilization
CLIP STUDIO ASSETS has a wide variety of materials.
If you search ASSETS for "skin" before painting the skin,
you'll find a variety of materials, including brushes, palettes, and textures, that you can use to paint the skin.
The provided palette allows you to paint skin in amazing colors without having to think about the colors yourself.
There are many brushes that can be used to paint skin,
and I used this brush to create the shine in this painting.
There's even a brush that can paint shaded thighs in one stroke.
I was able to finish this in about a minute.
If you're having trouble with painting, not just with skin painting,
take a look at ASSETS and you might find materials that will help you.
Paint using the 3D model as a reference
Have you ever had trouble understanding the shadows on a body?
It would be great if you had a figurine on hand, but some people may not have one.
In such cases, use a 3D model.
You can also adjust the lighting however you like, whether it's front lighting or back lighting.
When you paste a 3D material from the material palette,
it automatically switches to the object tool.
When editing 3D materials, use the object tool.
Click the wrench icon at the bottom right of the tool properties,
to display the \"Sub Tool Details\" palette.
If shadows are not displayed on the loaded model,
select something other than [Don't cast] from the drop-down menu to the right of the Shadow item.
By dragging the ball displayed in the palette,
you can change the direction of the light source.
You can also easily create backlighting.
You can also apply the shadow cast by another 3D model.
In the video, the 3D material for the character and straw hat were placed on the same layer.
Select the straw hat object,
change the setting to apply shadows in the [Light Source] item,
and check [Cast shadow of this model],
and the shadow of the straw hat will be cast on the character.
It can also create shadows cast by windows that fit the human body, something that would be difficult to recreate with a figure.
Use the 3D model's paint as is
Use Shadows
You can also use the shading of the 3D model directly to paint the skin.
This time, we'll use this material.
Once you've given your 3D material a pose, create a line drawing based on that.
After painting the base, hide the 3D model's outline and rasterize it.
You can turn the 3D model's outline on and off from [Sub Tool Detail] → [Outline]
by checking [Outline width].
Rasterizing creates a raster layer that you can draw or fill with a pen. **If you think you might want to change the settings of your 3D model later, rasterize the duplicated layer.
Clip the rasterized model to the base and use the blur or pen to adjust it to match the line art.
Adding Color
The skin will be gray as it is, so let's add color using a gradient map.
A gradient map is a function that allows you to replace and color the gradient color according to the shading of the layer.
(Reference: CLIP STUDIO PAINT Reference Guide)
For the purposes of this article, all you need to know is that you can change the color of a picture painted in gray.
This is also explained in this article.
If you search for "skin gradient map", you'll find a lot of materials.
This time, we'll use this material.
You cannot use the gradient map material just by downloading it.
After downloading, select the material and click the icon at the bottom right of the material palette to register it.
Select [Layer] menu → [New Tonal Correction Layer] →
[Gradient Map]
to create a gradient map layer.
The gradient map dialog will then be displayed,
so select the material you just registered.
Double-click the gradient you want to use,
and press [OK] to apply the gradient map.
You've now added color!
Gradient maps also make it easy to change the color later.
Double-click the icon
to the left of the gradient map layer to display the Gradient Map dialog again.
You can now change the color as many times as you like.
You could even make it red or green, or even a metal terminator.
If you want to use the shading of this material as is, the lines drawn on the 3D model will get in the way. You can hide them in the settings. Click Render Settings in Environment in SubTool Details to display the Render Settings dialog. Uncheck Texture → Use Texture to hide the lines (texture) on the body. Also, click the Lighting → Method pulldown to select the shading method for the selected 3D material from Gouraud, Phong, or Toon.
Conclusion
This time, I tried painting the skin using various functions and materials in CLIP STUDIO PAINT.
CLIP STUDIO ASSETS and TIPS
contain many ideas that I would never have thought of on my own,
so be sure to check them out when you get stuck.
