Subtool Controls
Eye Icons: Each subtool has an associated eye icon that can be clicked to toggle that subtool's visibility. If the eye icon of the currently selected subtool is clicked, it also affects the visibility settings of all of the other subtools. The selected subtool is always visible, regardless of the setting of its eye icon.
Arrows: From left to right respectively, these select the subtool above the currently selected subtool, select the subtool below the currently selected subtool, move the selected subtool up one place in the subtool list, and move the selected subtool down one place in the subtool list.
Select Up: The 'up arrow' selects the layer in the layer menu immediately above the currently selected layer.
Select Down: The 'down arrow' selects the layer in the layer menu immediately below the currently selected layer.
Move Up: The 'up and over arrow' moves the currently selected layer one layer up in the layer menu.
Move Down: The 'down and over arrow' moves the currently selected layer one layer down in the layer menu.
Append: Add another mesh as a subtool of this mesh. A dialog will appear showing currently loaded Polymesh3D objects, from which you can choose the mesh to be added.
Delete: Deletes the currently selected subtool. The rest of the subtools and the overall model are not affected.
Split: When a tool or subtool is partially visible, the split button will split it into two subtools, one composed of the visible part of the original subtool, and the other consisting of the hidden part.
GrpSplit: When a tool or subtool contains more than one polymesh groups, the group split button will split it into multiple subtools, one for each group.
Rename: Allows you to rename the currently selected subtool.
ProjectAll: Projects all visible SubTools into the selected subtool. Note, there is a fixed range that Project All will use. To ensure best results combine ProjectAll with the ZProject brush.
Extract: Extracts a new mesh from the masked area of the currently selected model or subtool, and puts it into the model's subtool list.
E Smt: Determines how smooth the edge of an extracted mesh will be. High smooth values will remove detail from the edges of the extracted mesh, which may or may not be what you want.
S Smt: Determines how smooth the surface of the extracted mesh will be (similar to extracting the mesh without smoothing and then using the Smooth brush on it.)
Thick: Sets the thickness of the extracted mesh. 0.01 is about right for cloth, 0.03 for leather, etc.
