3DCoat has three channels that you can paint at any given moment.
Before you’ll find out how each tool works in Paint Mode, you are to know about painting in Depth / Color / Glossiness channels, and also to know about color picking, and types of drawing.
This icons will, upon LMB clicking, toggle the channel on or off. If the channel is off, you will see a large “X” over the respective icon.

On the right you can see in the image those three icons. They are from left to right:

  • Depth: Use the depth slider to adjust the amount of extrusion to apply while drawing. Use the smoothing slider to adjust the amount of smoothing to apply while drawing with the SHIFT key pressed. To view menu use D.
  • Color: Use the opacity slider to adjust the amount of color to apply. Click to disable color. Use the button determines the rule for the draw color. To view menu use C.
  • Glossiness: Glossiness channel intensity control. Click to toggle Glossiness on or off. To view menu use R.

Use “~” key to quick-access the semi-transparent panel containing parameters for all the three channels in compact form (you can pin it anywhere on your working space).

Also if you hover over each icon you will notice that there are a few more options for each, which can also be controlled with your RMB + dragging up/down or left/right.

  • RMB and dragging your mouse up/down will change the intensity of your Brush.
  • RMB and dragging your mouse left/right will change the size of your Brush.

Depth


Point the cursor at the purple hued sphere and click. By clicking here you can toggle between turning the depth on or off.
If there is an “X” over the sphere, it will be toggled off.

Additive drawing option allows activating/deactivating additive application option when drawing lines. If Additive drawing is active, two lines are drawn one over another.
Notably, if the option is disabled, cross is made with objects drawn in the current layer only.

Red line on the pen cursor displays the depth of relief lying. Press “-” and “+” keys or mouse wheel (under corresponding adjustments in the “Preferences” menu) to see how the depth changes.
If the pen is of complex shape, less pressure should be applied to prevent steep overfalls of image height. On a side note, it would make it hard to present the entire object as normal-mapped low polygonal one, heavy geometry distortions will be seen.

With the help of “Smoothing” slider you can change the level of smoothing. By pressing SHIFT key green line will appear on the pen cursor and by pressing SHIFT “+” and “—” keys or MOUSE WHEEL (provided corresponding adjustments have been made in the “Preferences” menu) you can adjust the level of smoothing.

Color


Point the cursor on “Color” icon. By pressing on “grey X” sign you will forbid drawing color for the current texture. Pressing on a green sphere icon you enable editing in diffuse channel, but with no extra texture overlaid in the channel. If the texture is selected there are also folder icon and a texture-imbued square. Press on the folder to replace your texture.
The Opacity slider is the transparency applied to pen color while drawing. You can reduce or increase the transparency using hot keys “О” and “Р” accordingly. You can see that depending on transparency the segment color changes on pen cursor. The segment acquires blue color and its size depends on transparency.

Point the cursor on the drop-list to see the following. Here you can determine the rule of color selection for drawing. You can draw with a main color, or you can use a mix of the main and background colors:

  • Current color. Use the current color to draw.
  • Randomly one of two colors. Use one of two colors (current or secondary) randomly to draw.
  • Use random color between two. Use a random mix of two main colors.

Glossiness


By choosing the shining sphere icon you will enable drawing in Glossiness channel. With the help of Intensity slider you can change the reflective qualities applied while drawing. The hot keys “<” and “>” or mouse wheel (under corresponding adjustments in the “Preferences” menu) allow changing the Glossiness parameter quickly.

The Top Tool Bar menu is customized according to which workspace you are working on.

As some pen options are on the top menu bar, you’ll notice that when you change your tool, so will a portion of the menu bar. These options are: Soft stroke, Pressure Dependencies, Radius, Smoothing, Depth, etc…

Steady stroke: In this mode strokes will be more accurate because of additional smoothing of trajectory.

Invert Tool: Invert Tool. Toggle the function of the current tool. Like holding down the CTRL key.
Radius: This allows you to scale up and down the size of your pen in the viewport with a slider or by manually keying in a value. It is relative to the scale of the scene you have set.
Setup Tapering Parameters: Tapering allows to modulate or replace pen pressure with values got from our curve.

Focal Shift: This slider adjusts the crispness of the alpha, corrected around the center point. Higher values produce softer edges on most shapes (activate this option on Preferences).
Falloff: This allows you to control the brush with with a falloff curve, giving tighter control over the radial area the brush will affect depth.
Depth: This allows you to to turn the intensity of the depth of your strokes with a slider or by manually keying in a value.

Smoothing: This allows you to turn the intensity of the smoothing up and down with a slider or by manually keying in a value.
Opacity: This allows you to turn the intensity of the color channels transparency up and down with a slider or by manually keying in a value.
Glossiness Intensity: This allows you to turn the intensity of the Glossiness channel up and down with a slider or by manually keying in a value. A lower value produces a diffuse highlight, higher values produce a sharper highlight.
Roughness: Controls the sharpness of the reflections.
Metalness: Change the Metalness intensity. A higher value produces a higher reflectivity, lower values produce a lower reflectivity.

These three icons indicate what mode your style is currently in. You can toggle from one to the other simply by LMB clicking on the icon.

The mouse icon locks pen pressure to whatever value you have in the respective setting the icon is next to.
The Pen icon allows for pen pressure directly from your stylus. The lock Icon, will lock the “on screen” size of the pen. It is convenient when you want to change radius of pen simply moving the model back and forward.
The lock icon near depth slider allows you variety pen radius without variation of absolute pen depth. In standard mode radius and depth are proportional.

Minimizing on the Tool Bar

You can also collapse/expand settings on the tool bar, such as Falloff, Depth, etc.. This can be done by clicking in the immediate area around the setting you wish to minimize. The image here shows the area to click to achieve this.

Define how brush radius depends on brush pressure. Curve will be used only if brush radius is allowed to be dependent on brush pressure.


Taper Modifier: Tapering allows to modulate or replace pen pressure with values got from the curve. Of course you need to enable or disable dependency of radius or opacity on pressure to see the effect. Tapering itself just modifies pressure, but how you will use it - it is on your taste. Note that tapering length is in multiples of the current brush radius

Height/Color Limiter Conditions
Select how depth, color and Gloss of your brush strokes are affected by colors, height and other parameters. Remember to set to “None” when you finish using this option.


Anti-Bump Smoothing Option: This video demonstrates the new Anti-Bump Smoothing Option, available from the SHIFT or CTRL + SHIFT hotkey combination menus, when Surface mode sculpting in 3DCoat.

Creating Custom Brush Curves & Move Stamp Brush: This video demonstration covers two new features in 3DCoat. Including the ability to create your own brush alpha using a Curve Profile Editor, and then the new Move Stamp Brush (in the E-Panel). This allows you to preview the result, yet move it about the model until you're happy with the placement.
