This new brush engine lets you modify controls for the sculpting tools. You can also build new brushes or modify existing ones fine tuning to fit your needs.<\/p>\n\n\n\n

Buildup mechanism for sculpt brush Engine<\/h3>\n\n\n\n
\n\n\n\n

Buildup and non-buildup brushes act the same; the difference starts when you will stroke the same place many times:
– Non-buildup reaches some height limit; buildup grows infinitely (but slowly) if the modifier allows.
– The voxel color is applied to many tools: Blob, spike, snake, muscle, primitives, etc.
– You may now sculpt and paint simultaneously with all Voxel Brush engine-based brushes.
– All surface brushes based on Brush Engine got new parameter -> the influence area customization.
It is important to limit the brush influence in tight areas.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Render influence area:<\/a><\/strong> there may be times where you want to see a 3D preview of the area that’s being influenced you can check that. Some people may find that a little bit too obtrusive or distracting so you can uncheck that at any point.
Next is customized influence that’s going to allow you to squash or scale the top half or bottom half of that sphere as it either extrudes from the surface or is extended beneath the surface.
You can see how the top half is squashed based on the percentage set in the parameter.<\/p>\n\n\n\n

Modify brush parameters for the sculpting tools.<\/a><\/h3>\n\n\n\n
\n\n\n\n

There are a wide variety of brushes, each with a unique property.
To access Tool options, you need to click Edit brush parameters.<\/p>\n\n\n

Brush options for voxel & surface tools<\/a><\/h3>\n\n\n\n
\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n
\n

Instead of adding geometry based on the surface, you can use Camera Viewpoint to add\/remove geometry.
Almost all brushes have this as an option in the top left brush options menu<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div><\/blockquote>\n\n\n\n

Only available on Voxel Mode you can find this options:
\u2013 Voxel Paint:<\/strong> You may now sculpt and paint simultaneously with all Voxel Brush Engine-based brushes.
\u2013 Act as Vox Hide:<\/strong> any Voxel Brush Engine brush may be used as the Vox hide brush; just enable the very visible option in the brush. <\/p>\n\n\n\n

– Modify Connected:<\/strong>
– Post-smooth:<\/strong><\/p>\n\n\n\n

Tool Options Menus<\/h3>\n\n\n\n
\n\n\n\n

\u2013 Subdivision:<\/strong> This option is not supported if Modify connected is enabled. Uncheck \u201cModify connected\u201d.
\u2013 Brush Stroke:<\/strong> How sculpted stroke is applied.
\u2013 Misc Settings:<\/strong> Principally new buildup mechanism for Clay Engine. Now buildup and non-buildup brushes act the same; the difference starts when you will stroke the same place many times. Non-buildup reaches some height limit; buildup grows infinitely (but slowly) if the modifier allows.
\u2013 Sampling:<\/strong> How stroke position is applied.
\u2013 Modifiers:<\/strong> let you build your brushes.
Smooth (surface) brush mode:<\/strong> The voxel brush works similarly to surface brushes in this mode.
Smudge:<\/strong> Pull the surface along the trajectory.
Pinch:<\/strong> Pull all vertices toward the center of the brush.
Rotate:<\/strong> Rotate the surface under the brush.
Side shift:<\/strong>
Angulator:<\/strong> The Angulator picks two points \u2013 one on the left and one on the right side of the brush. Then it builds two planes from that point and snaps the surface to the closest plane. Also, it adds a little pinch to underestimate the sharpness of the angle.<\/p>\n\n\n\n

Alphas:<\/strong> The Alpha controls the shape of the brush. Alpha is a grayscale intensity map.
Add Brush Modifier:<\/strong> there are two selection methods, use what already exists in the alpha library or procedurally create new ones using the curve editor. <\/p>\n\n\n\n

Switch on “Use current alpha” to access the library of alphas (T hotkey).<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Switch off to use new procedural alphas.<\/p>\n\n\n

Dam Standard Brush Equivalent in 3DCoat:<\/a><\/strong> This video demonstrates 2 brushes in 3DCoat that are the closest equivalents to the Dam Standard brush in ZBrush, for those artists who have experience in the application.
A few tips are added regarding the usage of “Remove Stretching,” “Auto-Subdivide (dynamic subdivision beneath the brush) and the Magnify SL brush…which may often be used in conjunction with the Pinch Brush in 3DCoat.<\/p>\n\n\n\n
