Base Clay:<\/strong> The basic brush for the voxel brushes. Duplicate, give the proper name, and customize it. This tool does not depend on the Alpha, so there is no difference in what alpha do you use. You may edit the Brush parameters -> Modifiers -> Some Item ->Use current alpha<\/em> to use the alpha.
Wet Clay:<\/strong> This is similar to real clay. It consists of a clay effect and a little smudge.
Vox Smart Pinch:<\/strong> Vox Smart Pinch operates similarly to Smart Pinch in Surface Mode, where it detects angles in the surface to apply extrusion inwardly or outwardly + pinching automatically.
Vox Pinch:<\/strong> This option draws the surface area closer to the radial center of the cursor.
Usual Clay:<\/strong>
Vox Flatten:<\/strong> This mode flattens the surface beneath the cursor by raising or lowering points to a common plane.
Trim Smooth Border: <\/strong>
Soft Clay: <\/strong>
Thick layer:<\/strong> Clay effect without the constant increment (no buildup).
Vox Extrude:<\/strong> The extrude of the voxel’s surface.
Vox Buildup:<\/strong> Constant buildup of the surface while the brush moves.
Voxel Skin:<\/strong> This brush demonstrates the possibility to use alphas with mixed positive and negative extrusion. It depends on the checkbox “Surface-like mode” in Brush settings-> Modifiers. <\/p>\n\n\n\n

\n

Alphas imported from images (including .exr) may be mixed positive and negative, it allows making more realistic skin details. Negative alphas work for draw\/extrude-like brushes in sculpt room.<\/p>\n<\/blockquote>\n\n\n

Use [+] in the alphas palette, “Open texture, make round falloff” to add different types of skin\/noise: Alphas may be imported as rounds with accurate falloff, it simplifies making alphas from the raw textures a lot. This option available in alphas palette or using drag&drop.<\/p>\n\n\n\n

What’s the difference of Vox Clay, Base Clay and Wet clay<\/h3>\n\n\n\n
\n\n\n\n

The “Clay” family of brushes are designed to mimic real-world sculpting materials, with different behaviors regarding how they add volume and interact with the surface.<\/p>\n\n\n\n
