Cutout Editor toolbar reference

The Cutout Editor toolbar contains all high-level controls for editing the mesh.

Refer to Cutout Editor for more general information about this tool.

Points

The Points tools allow you to add, move, and delete vertices in the mesh. You can also generate a new mesh.

Control	Description
Add	Add points by clicking in empty space. You can also move existing points by clicking/dragging them.
Select	Select multiple points by drawing a selection box around them. To move them, click and drag a selected point.
Remove	Delete points by clicking and dragging over them.
Reset	Clear all points.
Mirror	Make the left and right side of the mesh identical. If you add a point on the right, a similar one is added on the left. Any points very close to the middle are snapped to the centerline. Deselect this option to disable the mirroring effect.
Generate	Open the options to generate a new set of points. If you generate points, any existing points are removed. For the best results, use the Straighten options before you generate points.
	Point density	Approximate how many vertices you want in the final mesh. This is approximate, as more or fewer vertices may end up in the final mesh depending on what it had to do to generate the correct outline.
	Generate slices with center line	Generate points in evenly spaced slices from bottom to top, with an additional point in the center.
	Generate slices	Generate points in evenly spaced slices from bottom to top.
	Generate adaptive points	Generate points evenly around the outside edge of the opaque parts of the current material.

Straighten

Straighten mode allows you to deform the texture UV space. See Straighten for more information.

Control	Description
Edit	Enable Straighten mode where instead of moving points and anchors of the mesh, you will be moving around the UV space that will be shown when switching back to any of the other tools.
Linear	Force the center two points of the straighten curve to line up between the start and end points, making the straighten area a rectangle.
Reset	Reset the straighten area to the entire material.

Anchors

The Anchors group allows you to add/edit mesh anchor points for where children will grow.

Control	Description
Add	Add mesh anchor points by clicking in empty space. You can also move existing points by clicking and dragging them. Each anchor point has a white line coming from it that indicates the growth direction of anything placed there. You can drag the white dot at the end of this line to set this direction.
Remove	Delete mesh anchor points by clicking and dragging.
Reset	Reset the anchors to default (none).

Paint

The Paint group lets you paint masks, vertex colors, and separate sections onto the mesh. Use the Brush options to control how you paint.

Control	Description
Mask	Paint a mask to remove polygons from the mesh.
Color	Paint a color onto the vertices. Choose the color from the Color Editor.
Section	Paint or remove sections that can be individually manipulated. This option currently only works on Frond generators. For more information, refer to Manipulate mesh sections.
	New section	Add a new section.
Clear/Fill	Choose clear or fill options that align with the selected paint mode.
	With Mask selected
		Clear	Clear all masking.
	With Color selected
		Fill with black	Paint all vertices black.
		Fill with white	Paint all vertices white.
		Fill with color	Paint all vertices with the current color.
	With Section selected
		Clear	Clear all markings from the current section.
		Fill	Fill the current section with marking.
		Delete current layer	Delete the current section.

Mesh options

Control	Description
Snap threshold	Control when points are automatically moved to avoid very skinny triangles in the mesh, which can cause sub-par results when the mesh is deformed with fold or curl.
Tessellation	Choose the tessellation style.
	Triangular	Tessellate in a triangle pattern.
	Split	Tessellate in a triangle pattern and iteratively split the longest triangle edges to create a more regular mesh.
	Grid	Tessellate in a grid pattern.
Tess. amount	If you wish to have more triangles in the mesh so it will work better for fold, curl, or other deformations, add them using the tessellation control. It will intelligently subdivide the existing triangles.
Refine edges	Add tessellation to the outside edges of the mesh.
Tessellation	If you wish to have more triangles in the mesh so it will work better for fold, curl, or other deformations, you can add them using the tessellation control. It will intelligently subdivide the existing triangles.
Tess. style	You may choose to tessellate using triangles, or to tessellate into a grid pattern.
Angle	If your texture/material isn't quite aligned with the y-axis, use this option to rotate the final mesh. The new y-axis is indicated by the orange line. You can also change the rotation angle with the Straighten tool.
Double-sided	Occasionally you will want a double-sided mesh, which can often light better on things like palm fronds. This option will duplicate the mesh and flip the new one to face the other way.

Brush

Control the brush that applies or removes masks, vertex colors, or sections as determined by the Paint options.

Control	Description
Mark	Paint the selected option onto the mesh.
Erase	Erase the selected option from the mesh.
Size type	Set how the brush scales.
	Absolute	The brush size stays the same regardless of zoom level.
	Screen	The brush size scales as you zoom in and out.
Size	Set the size of the brush.
Falloff	Set the size of the falloff area on the brush. The effect gradually decreases across the falloff area. This option is not available with Mask painting.
Opacity margin	Enable this option to stay within the bounds of the material’s opacity map. Use the slider to increase the paintable area around the opacity map.

Material

This option sets the material shown in the preview and affects the aspect ratio of the mesh created (to match the material). If you create a new cutout mesh by selecting the Edit button in the Materials Bar, this option will already be set to the correct value.

Control	Description
UV warnings	Set the threshold for warning when there aren’t enough vertices in the mesh to accurately represent the UV space deformation when Straighten is being used. The warning displays as a yellow overlay.
Show all meshes	If this material has multiple meshes assigned, this option will display them all in a different color so you can see everywhere this material is being used in meshes.
Show color	Display the color channel from this material, possibly modulated by the opacity.
Show opacity	Display the opacity channel from this material, possibly modulated by the color.
Show height	Choosing this option will make the height map from the material show, overriding any color or opacity.
