The Advanced Export Options window gives you full control of the available export settings in SOFTBOX (HDRI) for TurboCAD. The window is opened with your default export settings already loaded. The default export settings can be changed under the application preferences. See Advanced Export for more information on these settings.

This is the target version of TurboCAD you will be exporting to. In general, TurboCAD versions that share the same Lightworks version (i.e. LW Version 7050000) will result in the same exported data. Newer versions of TurboCAD will also automatically convert data files exported to older versions when they are loaded into TurboCAD. So it's not always crucial to use the exact version when exporting. TurboCAD will let you know if there are any issues during import.
This setting controls what is visible in the background of your rendered scene as well as in materials with reflective or refractive shaders.
Environment is the simplest of the two choices. Checking this option tells TurboCAD to render your scene with the images that make up the assigned cubical map visible in the background and in any reflective or refractive materials present in the scene.
Ray Cube is more complex and offers better control over what is visible and where. When selecting a ray cube as your background you are given the ability to choose reflected and refracted backgrounds that are different from the visible background in your scene. This means you can choose a solid color background while still getting SOFTBOX (HDRI) reflections and refraction in your materials.
The Size and Center settings are available when Fixed Cube is selected as the Global Environment Type. These settings give you control over the size and position of the cubical map relative the coordinate system of the scene.
A cubical map consists of six sides or views. They are referred to in TurboCAD's Render Scene Environment Editor as top, bottom, front, back, left and right. The same naming convention is used to describe the Standard Views available in TurboCAD as well (with the exception of the World Plan and Isometric views). Because these share the same names one might expect an HDR image assigned to the front of a cubical map to illuminate what is considered by the standard views to be the front of the scene. However, this isn't the case. Checking Align Environment With Standard Views will align your cubical map to the standard views at export time which can alleviate some confusion for new users.
Image based lighting, especially with high quality settings, can require long render times. You can still benefit from the realistic reflections of a cubical map without the longer render times associated with image based lighting by using a different luminance to illuminate your scene. Checking Export Non-IBL Luminance will tell the Cubical Map Builder to create a luminance data file during export containing distant luminances that approximate the lighting setup of your cubical map. See Using Non-IBL Luminances for more information.
The text in this field will be used to create a category for your cubical map when it loaded into TurboCAD. Subcategories can be created by using a "\" between categories (i.e. "Main Category\Subcategory"). This field is automatically filled with the name of the category that holds your cubical map in the Navigation Tree.
