LipService/LBrush Tools

The fist three buttons of the LBrush shelf activate the LBrush Tools.

1. Sculpt Tools. LipService/LBrush currently has six sculpt tools. 'Sculpt Tools' and 'Brush Tools' activate the brush. The Plug-in has a spherical brush. The main difference between these two groups of tool is what vertices are affected when you performing the strokes. Sculpt tools use a static selection, meaning they affect only the verticies that were within reach when you first clicked down.

2. Paint Tools. Tools of this group constantly check for verticies which are within current reach..

3. Selection Tool. This tool is very similar with standard Maya selection tool. It allows to modify only selected sets of sub-objects (faces, vertices).

Important Notes:

  • LipService/LBrush plug-in works only with polygonal surfaces now.
  • You should select single object and then you can activate the LBrush Tools.
  • When you use one of these tools to some object the fist time the LBrush Deformer Node is created and connected to your object
  • When you have LBrush Deformer Node connected already and AE is opened activating the tool will not show the tool properties, double click the tool button on the shelf for it.

Sculpt Tools

LBrush Sculpt Tools affect the vertices that are within reach of the brush when the left mouse button was pressed (stroke was started)

Three groups of controls are on this rollout. Tool Modes toolbar, Brush Size slider group and Falloff group..0

  • 'Brush Size' defines the size of brush relatively to viewport. So for example size of 0.3 makes the brush makes the brush occupies 0.3 of width your mouse cursor is moving in.

  • 'Falloff' group allows you to define the strengths of field that influences the vertices inside the brush (you can see its actions in 'Translate Tool' demo movie).
     

 1. Translate Tool

This tool is selected by default. Use it to move the mesh vertices relative to the view.

2. Rotate Tool

Rotates the vertices around the viewing direction. (when you the drag the mouse right vertices are rotated clockwise and rotate counterclockwise when drag left)

3. Inflate Tool

Moves the vertices in vertex normal direction. Dragging the mouse right is inflates out the surface, dragging left restores to original shape cached on mouse button down.

4. Smooth Tool

Smoothes the surface. Dragging mouse right makes surface more smooth, dragging left restores to original shape original shape cached on mouse button down. You can adjust the strength of this tool changing the Number of Tool Iterations in LBrush Global Preferences.

5. Sharpen Tool

Sharpens the surface. Dragging mouse right makes surface more sharp, dragging left restores to original shape original shape cached on mouse button down. You can adjust the strength of this tool changing the Number of Tool Iterations in LBrush Global Preferences.

6. Blend Tool

Mixes your mesh with some other target when dragging mouse right, dragging left restores the original shape cached on mouse button down. The 'NEUTRAL' is selected as blend target by default you can pick any other target from the 'Blend Layer' drop down below in 'Common Properties' rollout.

This can be very useful for example for undoing sculpting on regions of the face by selecting the 'neutral pose' as a target. You can switch targets at any time and it will not affect previous blends

Paint Tools

LBrush Paint Tools affect the vertices that are within reach of the brush as the mouse is dragged.

There are three groups of controls that are used by all tools of this rollout.

  • 'Brush Strength' defines the brush influence on he vertices that are getting in. If you are using wacom tablet stylus pressure will be multiplied by this value.

  • 'Brush Size' defines the size of brush relatively to viewport. So for example size of 0.3 makes the brush makes the brush occupies 0.3 of width your mouse cursor is moving in.

  • 'Falloff; group allows you to define the strengths of field that influences the vertices inside the brush (you can see its actions in 'Translate Tool' demo movie).
     

1. Push Tool

This tool is selected by default. It shifts the vertices in direction inside the object (or outward the user due to 'Transform' settings) when stroke is performed. 

2. Pull Tool

This tool shifts the vertices in direction outside the object (or toward the user due to 'Transform' settings).

Two options can be used with Push/Pull tools:

  • 'Transform' radio buttons group
    'Along view direction' choice makes vertices are Pushed/Pulled along the direction from eye to brush center.
    'Along normals" makes vertices are Pushed/Pulled along vertex normals.
     

'Accumulation' radio buttons group
'Off' is limiting the distance vertices can be Pushed/Pulled during one stroke. So if you drag mouse multiple times at the same place after some number of drags vertices will not move any more.
'On' makes vertices free to be Pushed/Pulled more and more when the same place is painted during the continuous stroke.

3. Pinch Tool

Shifts the vertices that get to the brush when stroke is performed toward the brush center.

4. Stretch Tool

Shifts the vertices that get to the brush when stroke is performed outward the brush center.

 

5. Smooth Tool

Smoothes the part of surface that gets to the brush during the stoke.

6. Sharpen Tool

Sharpens the part of surface that gets to the brush during the stoke

7. Blend Tool

This tool works in the same way as Sculpt Blend Tool but affects the vertices that get into brush when stroke is performed.

8. Smudge Tool

This tool drags the vertices in direction of moving the brush when stroke is performed

LBrush Tools Sample on the Web

Common Tool Properties

  • 'Enable Gliding' checkbox makes the brush is gliding on the object surface when muse if moving it makes brush position more visual especially of you see your object from different viewport and can see exact brush location on object surface before stroke is started. This option is turned on by default.
  • 'Blend Target'  drop down. The names of phoneme targets of node is sculpted are listed here (Standard and Extra as well). The selected target is used by Sculpt Blend and Paint Blend tools to blend the current shape with.
  • 'Symmetry' radio buttons
    'X', 'Y', 'Z' makes the action of all the tools symmetrical relatively correspondent planes in object space;
    'None' is default option - turns the symmetry off.

Selection Tool

You can select some part of object and then only selected faces/vertices will be affected by LBrush tools. You can also create named sub-object selections and use it with LBrush.
