Advanced Export Options

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.

Export Version

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.

Background Type

2. Background Type
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.

Intensity / Angle / Color

3. Intensity / Angle / Color
The Intensity, Angle and Color values apply to the background type that you have selected.
Intensity affects the brilliance or brightness of cubical map images that are visible in the background and in materials.
Angle allows the cubical map to be blurred slightly.
Color is available when Ray Cube is the selected background type and allows you to choose a solid color that will be the visible background of your scene.

Global Environment Type

4. Global Environment Type
This option lets you choose between a Cube or Fixed Cube as the Global Environment Type.

Size / Center

5. Size / Center
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.


6. Alignment
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.

Export Non-IBL Luminance

7. Export Non-IBL Luminance
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.

Enable Shadow Transparency

8. Enable Shadow Transparency
This option allows for basic Shadow Transparency through transparent objects in a scene.

Max Intensity

9. Max Intensity
The Max Intensity value is used to match the intensities of light sources in a Non-IBL Luminance export relative to those represented in a cubical map.

Intensity Units

This setting controls the Intensity Units used in a Non-IBL Luminance export. The available options are Empirical, Lux, Kilolux, and Footcandle.

Shadow Type

11. Shadow Type
Shadow Type provides control over the shadow softness of Non-IBL Luminance exports. The available settings are None, Hard, Soft, Softer, and Softest.

File Name

12. File Name
The text in this field will be used to name exported cubical maps and their data files. This field is automatically filled with the name assigned to your cubical map in the Navigation Tree.


13. Category
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.

Export Path

14. Export Path
The export path is where your cubical map a luminance data files will be created and saved during export. Press the button to the right of the input field to browse to the folder of your choice.


15. Buttons
Pressing the Export button will initiate the export operation using the current export settings.
Pressing the Preview button will launch the Export Preview window.
Pressing the Close button will cancel the export operation and close the Advanced Export window without exporting any data.
