Version 6.5

The main changes in SOFTIMAGE|XSI 6.5 are the new packaging:

• The Essentials package now includes Hair and Syflex Cloth.

• The Advanced package includes additional render nodes.

In addition to the new packaging, there are some other enhancements described below. See also the “What’s New” section of the SDK documentation.

Crosswalk

The XSI 6.5 installation does not include the most recent Crosswalk point release. You can download and update the Crosswalk toolset for free from Softimage.com/downloads. Update all of your integrations with Crosswalk version 2.05 (or later).

See What’s New in Crosswalk (XSI Wiki).

Instance Master Visibility

The Instance Master Hidden parameter on the Rendering tab of the Visibility property editor now also hides objects that are parts of a model instance master in the viewport displays, in addition to when rendering.

Snapping

You can now snap to components on instances. This includes snapping the temporary tool pivot.

Unique UVs/PolyPack

There is a new Packing Method called Tight which lays out polygons better than the old method (now called Rows and still available for backwards compatibility).

Editing Texture UVs

The Apply to All UV Sets in Texture Editor option in the Transform UVs property editor allows you to numerically transform all texture samples of all UV sets displayed in the texture editor at once. This is useful, for example, if you have several objects sharing a single texture, and you want to transform them in unison so that they share a portion of a different texture.

Note that this feature and the entire Transform UVs property editor was removed in version 7.0 because you can now edit multiple UV sets in the texture editor, either interactively or using the U and V number boxes.

Satellite Support for RenderMap

RenderMap takes advantage of satellite rendering, if it’s available. The default tile size is 32. You can change this value using the TileSize parameter of the RegenerateMaps() command. Changing the tile size can affect the rendering speed, depending on the complexity of the objects, the size of the maps, and the number of rendering machines and their speed. For more info about RegenerateMaps(), see the SDK guides.

Tangent Maps

The Tangent Op property has a new parameter: you can turn off Encode Binormal Sign in Alpha to force the alpha to be 1.

HDR Support in RenderVertex

The PrecisionDatatype parameter in the RenderVertex property editor lets you specify Byte or Float when baking various surface properties into vertex color properties.

HDR Support for Vertex Colors

The DataType parameter in the Vertex Color property editor lets you specify the precision used for storing color channel values. For example, you can use float values for more precision in tangent maps or for storing HDR values.

Audio Playback

The new Play Audio at Display Refresh When Scrubbing option on the Playback and Audio page of the Interaction Preferences property editor toggles the audio behavior with respect to the viewport display synchronization when scrubbing.

When this option is on, the audio is played only after the viewport display update calculations have finished.

You may want to select this option when the geometry in your scene is heavy. In these cases, it can take longer for the viewport to update, which can cause a gap between the audio and the visual update. This option helps synchronize your audio with animation under these conditions.

Drag Force Option

The Radius option in the Area section of the Drag force property page has been adjusted so that it is now available only if you first select the Assume Size option.

Environment Variables

XSI_GTK_INIT_ON_STARTUP performs gtk_init() when XSI starts up. This can avoid some compatibility problems with plug-ins that use the GTK library.
