Hovering your Brush over a layer, you can see a dashed-downward facing arrow. LMB click to reveal the Layer Blend panel. You can also access the panel from the menu Window>Popups>Layer Blending.
This panel contains a more advanced set of parameters. Let’s take a look:

Lock texture: Locking texture allows locking color/depth texture over the layer regardless of its resolution. Texture at its current state will be saved to disk. As soon as you will change the resolution of the texture the locked texture will be used instead of current layer pixels resampling.
It is very important if you want to attach materials to layers and paint in low resolution. In this case occlusion, cavity and the normal map should be kept in original resolution. This function helps to keep important layers in original resolution.
Lock transparency: This lets you draw on a Layer without changing its transparency. Essentially, it lets you edit the current colors on a Layer without adding more.
Use as Weight Map: A very useful feature for painting weight maps directly inside of 3DCoat. While you’re not painting weight maps directly, you use image based painting, but if you set 3DCoat to use for this parameter, it will then convert the greyscale values to whichever value range you specify in this drop-down list. Values 0..100% will convert black to 0, and white to 100. Values -100..100% will convert black to -100, and white to 100.
Use this layer as weight map for LWO export. The weight map will be created with the same name as layer's name.

  • No: No override are performed.
  • values [0..100%]: Override depth of all previous layers with current one using color alpha..
  • values [-100% .. 100%]: Additional height for the layer to override depth of previous layers. It works only if “Replace depth” used.

Emboss power: A multiplier effect to increase the layer’s depth value. If the value is an extrusion, the extrusion will be higher. If the value is a cavity, the cavity will be deeper.
Replace depth: Override depth of all previous layers with current one using color alpha.
Layer Height: Additional height for the layer to override depth of previous layers. It works only if “Replace depth” used.

Depth/Color/Gloss/Metalness Opacity: Control the opacity for the layer’s respective value. This is mirrored from the Layers panel for convenience.

Depth Opacity: Depth modulator.
Opacity: Color Opacity Modulator.
Contrast: Control Contrast of selected layer.
Brightness: Control Brightness of selected layer.

Gloss/Roughness Opacity: Additional Glossiness modulator for the transformed area.
Additional glossiness: A multiplier to increase the layer's Glossiness value.
Gloss Modulator:
Roughness Modulator:

Metalness Opacity:
Additional Metalness:

Clip Mask Layer: Clip Masks are used, when you wish to mask a selected layer, with another layer. In this function you can specify the layer you want to use to Clip Mask the selected layer. Using the Invert Clip Mask function, will invert the clipped area. Note that channels from one layer, will mask the other. For example, Color channels mask only Color. Depth channels only mask Depth, Gloss, etc..

This function is very good for when you have a detailed painting that looks new in appearance, and you wish to “dirty it up” or make wear and tear. You can use one layer to paint the areas you wish to have wear and tear, and use it to Clip Mask the painted layer with all the details you want to be worn.

Clip Mask Layer: This drop-down list enables masking of the current layer with another one. Color, depth and Glossiness of the current layer will be clip masked by the selected layers color opacity. Transparency and depth of the current layer will be modulated by selected layer transparency.
Invert Clip Mask: An inverse Layer opacity will be used as a mask.

Layer Blending PopUp: This video is a brief demonstration of the Layer Blending Pop-Up panel in 3DCoat. It is meant to make quick layer adjustments right inside the layer panel, without having to switch back and forth (between panels).
