SoTransformSeparator(3) on Linux
The text 11e1dbdc89e0, as Debian 8 (Jessie) shipped it.
The SoTransformSeparator class is a group node preserving the current transformations. This node works like the SoSeparator group node, except that it only stores and restores the current model matrix transformation. Other appearance settings, like materials, textures, cameras, lights, etc, will affect the remaining parts of the scenegraph after traversal, just like as for the SoGroup node.
