Features Tab - Edit/Build Mode

This page covers the Features tab of the toolbox window in Edit and Build modes. This tab is shown in the image to the right. The upper section of this window is described here.

In Edit mode, some fields will be unavailable if the object is not modifyable.

NOTE: The term “Object” is used to refer to a single unlinked prim, or to a linked set of prims.
Most of the settings below can only be applied to individual prims; they will be disabled if you are editing a linked set.
Note that the overall properties of a linked set are the same as the properties of the root prim.

There are several groups of settings here, mostly unrelated to one another.

Flexible Path

Applicable to boxes, cylinders and prism types, this makes the prim flexible (usually known as a flexi prim). Such prims are usually path cut and hollowed. Flexible prims are commonly used in clothing attachments like capes, for flags and other wavy things. Flexible prims are automatically made phantom.

Flexible prim characteristics are as follows:

  • Softness: Controls the stiffness of the prim on a scale of 0 to 3, where 0 is the most stiff and 3 is the most soft.
  • Gravity: Controls how hard gravity pulls down on the prim. If you enter a negative value, gravity pulls the object upward instead.
  • Drag: Controls how much drag the atmosphere appears to exert on the prim when it's moved.
  • Wind: Controls how much this prim bends in response to the current region's wind.
  • Tension: Controls how much force is pulling the top of the prim away from its base.
  • Force X/Y/Z: Controls how much artificial force is applied on the prim, from different directions.

[To Be Done - when information is available]


Cause the prim to emit light. In order to be able to see the light, you need to have Preferences → Graphics → General → Local Lights enabled.

  • Color: Click this to open a color picker, from which you can select the light color.
  • Intensity: Sets the initial brightness of the prim; the possible values are between 0 and 1.
  • Radius: Specifies how far the light travels, in meters. The maximum is 20m.
  • Falloff: Sets how quickly the light's Intensity fades as it travels to its outer Radius. Lower values are more gradual.


For general information on projectors, please refer to this SL page.

When you have Lighting and Shaodws enabled (in PreferencesGraphics, then you can make use of projectors. In the Features tab of the edit window, you will see additional fields in the lower right.

  • Texture: This is the texture to project. Clicking it will open the Texture Picker.
  • FOV: The FOV setting defines the field of view of the projector, in radians. The field of view is the angular width of the cone of light projected. The possible range of values from 0.0 to 3.0 correspond to widths from 0 degrees to approx 172 degrees (almost a hemisphere of influence). Fidelity of shadows caused by a projector may degrade as the FOV becomes larger.
  • Focus: A projected texture appears blurrier the further the projection point is from the projector. The Focus value controls how attenuated this effect is. Positive values keep the projection sharper for farther distances, negative values make the projection start to blur at a closer range.
  • Ambiance: Ambiance adds a very blurred version of the projected image to all faces within the cone of influence, regardless of whether they are in shadow or facing away from the projector. The goal is to roughly simulate light influence being diffused in all directions by surfaces receiving a projected image. Thus it is acceptable that this be even brighter on faces facing away from the projector. The brightness of this effect is proportional to the Ambiance value.
