Tree Window properties
The Window properties control viewports, background images, and rendering settings.
To access the Window properties, right-click in the Tree Window viewport and select Window > Properties or select Window properties from the Property Bar when nothing is selected in the viewport.
Viewport
The properties in this group control the layout and rendering of the viewports.
Layout
Set the number and arrangement of the viewports. Choose from these options: One, Four, Two (over under), Two (side by side).
Grid lines color
Set the color of the grid lines.
Grid spacing
Set the amount of space between each grid line.
Lightmap view %
Set the size of the lightmap preview image. This property only works in Lightmap render mode.
Background
Style
Set the background style.
| Property | Description |
|---|---|
| Ambient light | Use the ambient environment for the ground and the sky. |
| Solid color | Set the background to a solid color using the Color property. |
| Full frame image | Set a background image with the Image property (some of the image may not be visible, depending on the aspect ratio). |
| Letterboxed image | Set a background image with the Image property and ensure that the whole image fits in the background, letterboxing if necessary. |
| Stretched image | Set a background image with the Image property and ensure that the whole image fits in the background, letterboxing if necessary (image aspect ratio is ignored). |
| Spherical panorama | Set a spherical panorama image for the background with the Image property. The image must be twice as wide as it is tall and formatted according to standard spherical (sometimes called 3D) panorama definitions. |
Color
Set the color for Solid color background rendering.
Image
Select an image file for the image-based background rendering styles.
Panorama Adjustments
Brightness
Increase or decrease the brightness of spherical panorama backgrounds.
Contrast
Increase or decrease the contrast of spherical panorama backgrounds.
Rotation
Rotate the panorama about the Z axis.
General Rendering
The properties in this group control render states and icon size.
Transparency
Set the transparency algorithm.
| Property | Description |
|---|---|
| Best available | Alpha testing with alpha to coverage (A2C) if the hardware permits. |
| Alpha test only | Alpha testing only. |
| Blending only | Alpha blending (artifacts will appear and geometry is not sorted). |
| Alpha testing and blending | Both alpha blending and alpha testing are on at the same time (artifacts will appear and geometry is not sorted). |
| None | No transparency rendering is enabled. Render mode shaders may still implement alpha testing. |
Anisotropic filtering
Set the level of anisotropic texture filtering.
3D icon scale
Scale the size of 3D icons (most notably forces) in the scene.
Normals scale
Scale the size of vertex normals in the scene. This option only works when normals are enabled in the Tree window toolbar through Show > Normals.
Manipulator
The properties in this group address the 3D manipulator used to move scene objects (most notably forces, force meshes, and the Fan and Light objects).
Mode
Set the type of transformation the manipulator performs.
| Property | Description |
|---|---|
| None | No manipulator appears. |
| Transform | Use the manipulator to move the object along the X, Y, or Z axes. |
| Rotate | Use the manipulator to rotate the object. |
| Scale | Use the manipulator to make the object larger or smaller. |
Coordinate system
Choose between global, local, and parent coordinate systems for transformations.
Size scale
Increase or decrease the size of the manipulator.
Screenshot Safe Frame
The screenshot safe frame sets an aspect ratio that can be used to guide all image exports. Use the same aspect ratio in your image exports to match the overlay.
Show
Set all image exports to the aspect ratio defined by the width and height values. Displays a red box in the Tree window to indicate how the aspect ratio aligns with the camera.
Width
Set the width value used to compute the screenshot safe frame aspect ratio.
Height
Set the height value used to compute the screenshot safe frame aspect ratio.
User Shader Constant 1
The properties in this group upload as a shader constant named g_vExperimental1 that you can access if you write custom render modes. Use these options to experiment with shader values without having to recompile the shader. These values are saved in the .spm file.
X
This value is uploaded to the shader constant g_vExperimental1.x.
Y
This value is uploaded to the shader constant g_vExperimental1.y.
Z
This value is uploaded to the shader constant g_vExperimental1.z.
W
This value is uploaded to the shader constant g_vExperimental1.w.
Force debug
Prompt the force-based mesh crawling algorithm to record and display debug information. This debug data can help you figure out why something isn’t working as expected and adjust the model accordingly.
