Lightworks Luminance Properties

Most Lightworks Luminance documentation is available via a separate help file accessed from within TurboCAD. You can access luminance properties via the Properties window of an object (see Object Properties),or by using the Luminances Palette

Note: If you are specifying luminance for the overall drawing, use the Render Scene Luminance. Drawing luminance can be applied either to the WCS (World Coordinate System) or UCS (User Coordinate System).See WCS and UCS.

Category: Three categories are provided for you, but you can create new ones. Single: Defines only one light type. Complex: Defines two or more lights. Floresc Architec AV: A set of light types representing realistic lights, based on .ies files from Lithonia Lighting. These files are stored in the Luminance\Photometric\ies folder. Luminance: This field depends on the category. See the relevant section for details. Edit Luminance: Opens the Render Manager. Load to render Luminance only: Check if you want to view only the object lights, and not the object itself.

Light Types

There are several types of lights you can use to define an object's luminance. Each type has relevant parameters such as intensity, color, direction, and location. Ambient: Illuminates all surfaces equally, regardless of orientation. Area: Simulates a luminous surface. Area Goniometric: Combines area and goniometric shaders, but models only sky light that passes through portals, such as a window or door. Distant: Light that is constant and parallel (non-conical). Eye: A light source located at the view point. Goniometric: Directional light, whose direction is specified by an .ies file (a text-based file). This luminance is useful for creating lighting based on manufacturers' lighting data, such as room lights, building lights, and street lights. Point: Light from a selected position. Projector: Projects a graphic image onto a solid object. An image file with full path must be specified. Simple Environment: A light shader that uses an environment map to light a scene. Simple Sky: A simplified sky shader which models the illumination from a uniformly bright, single-color, hemispherical dome representing the sky. Sky: An area light that simulates sky light, providing soft and natural shadows. This light is modeled as a hemisphere of infinite radius, positioned above the center of the model. Spot: Provides directional light that is constrained to a cone. Sun: Projects a spot light from a very distant point, to simulates outdoor sunlight. You can combine Sun and Sky lights for a realistic rendering effect.

Single Luminance

Defines only one light. You can select one of the provided luminances, or create a new luminance via the Luminance Editor . Examples of Single Luminance light types are shown below.

Lightworks Materials

Default UI Menu: Options/Materials

Ribbon UI Menu:

Creating a New Lightworks Material

You can create a new material in two ways: modifying an existing material, or creating a new one from scratch.

Modifying an Existing Material

In this example, the cylinder has the material "Stones - Granite Sierra" and the plate below is "Metals - Antique Brass."

1. To create a new material from an existing material, find the existing material in the Render Manager.

1. Then right click and select Copy Material Here.

1. Assign a name for the new material. It will be placed in the same category as the original.

1. In the Pattern category, increase the Scale (which is the size of the repeated image, in drawing units), and change the various mineral colors.

Wrapping an Image

If you have your own image you want to use as a material, this is defined in the Pattern category. This example uses a ceramic tile:

1. In the Editor, create a New Category.

2. Assign the name "Tiles."

1. Within the "Tiles" category, add a new material and call it "Beige Floral ".

1. For the Pattern, select "Wrapped Image"

1. Click the Browse icon next to File name.

1. In the Open dialog navigate to an image and select it.

1. For Reflectance, use "Matte" with a high Ambience Factor.

1. Use "Auto Axis" for Wrapping.

New shader Displacement*Wrapped normal map* is added in Lighworks.

Editing Lightworks Material

Default UI Menu: Options/Materials/Edit LightWorks Materials

Ribbon UI Menu:

Each material has five categories of parameters you can set: Pattern, Reflectance, Transparency, Texture and Wrapping. Not all categories are used for each material, only those that are relevant.For more information on Materials HDR, HDRI, Luminances and all other Lightworks.

1. Select a material in the Materials Palette
2. Right click and select Edit Materials.
3. When the Render Manager appears click the small green help button. This will open the Lightworks help, which is replete with details on functions and settings.

In the Preview section, you can change the shape and orientation of the preview object. Under Options, you can toggle the display of the preview object or desk. If Auto Update is checked, the preview will update each time a change is made (otherwise you must click the Preview button). The toolbar on the right side of the editor allows you to specify the elements of the preview. You can navigate within the preview window using the center mouse button. You can also see approximately how the material will appear on an object by entering a value into the Model Size field. Simply specify a size that is close to the size of the object to which you will be applying the material.Alternately, you can use the selection arrow under the preview. This will show you exactly how the material will appear on the selected object.

Warning: If the selection arrow is the specified option for the preview object, and no object is selected, you will get a warning that a preview cannot be generated. This will also happen if the selection arrow is the default and you open the Render Manager with no object selected.

Pattern

Note: TurboCAD has several defined patterns, but if you want to apply your own image as a pattern.

The first set of parameters in the Render Manager is for the material's pattern. For example, look at a Brick material. In this example, the pattern is "Wrapped texture brick."

This pattern is defined by dimensions and colors specific to bricks and mortar. For granite, the pattern parameters are related to mineral colors.

And for wood floors, the pattern parameters are for planks and grooves.

Materials such as glass have no pattern; the pattern is defined as "Plain."

To see the entire list of available patterns, open the drop-down menu. Each type of pattern has its own set of unique parameters.

Reflectance

This category defines a material's luster: its brightness, polish, dullness, etc. For example, a brick's reflectance is "Matte" - it is flat and does not reflect light.

Reflectance of most metals is "Conductor" - a set of parameters designed to simulate how metals interact with light.

Glass has its own Reflectance settings.

Some stone materials have "Mirror" reflectance to simulate shininess.

Transparency

This category is relevant for transparent glass and plastic materials. For example, "Eroded" transparency simulates a bumpy or uneven glass surface.

Not all glass or plastic materials have Transparency defined. For example, "Tinted Glass" is smooth, and its transparency is actually defined as part of the "Glass" reflectance.

This is a good example of how complex, and powerful, the TurboCAD materials engine is. You can get similar results by defining parameters in different categories.

Texture

This category enables you to make a surface appear rough or bumpy. The rendering engine simulates shadows along the surface to create the textured effect. For example, you can define a Leather texture. "Ice" is defined with a rough texture.

Wrapping

This category defines how a pattern or image wraps around surfaces of a 3D object.For materials, such as Granite, the wrapping is defined as "None," which pastes the pattern without distortion onto faces along the three major planes.

The "UV" wrapping is similar to "None" except that you can specify how the pattern is scaled. With "Auto Axis" the pattern is oriented according to the WCS, regardless of where the faces of the 3D object are located and oriented. You can also specify the axis along which the pattern will be projected.
