Renderworks shader parameters

Object Attribute

Selects the object’s fill color attribute to apply as a color texture

Image

Selects an imported image to apply as a color texture; the image can also be tinted with color (see Using an image in a texture shader)

Color

Specifies a color to be applied as a texture

Color

Click the color box to select the shader color

Brightness (%)

Lightens or darkens the selected color

Fresnel

Can be used to create a texture with a somewhat fuzzy appearance, like that of a pillow that appears slightly darker or lighter on its edges

Edge Color

Select the edge color by clicking the color box

Center Color

Select the main color by clicking the color box

Bricks

Creates a variegated brick pattern

Scale (%)

Specifies the size of the bricks relative to the texture Size

Colors

On the Bricks, Gaps, and Alt Bricks panes, click the color boxes to select color variations within a brick/gap, or choose the same color for no variation

Choose Image

On the Bricks, Gaps, and Alt Bricks panes, click to use an image for the brick or gap texture. The chosen image is randomized to show no repetition on the textured object, so each brick/mortar joint will look realistically unique.

For the completed brick surface to display correctly, the brick image should show only the flat face of a single brick or a portion of a brick, without any mortar joints. The gap image should show only mortar without any brick. Images of clay tiles and other similar objects can also be used in place of a brick.

Delete Image

Removes the selected image from the shader and uses only colors to create the variegated pattern

Image Blend (%)

When an image is used, specifies the blending between the image and the colors selected, to enhance the randomization of the resulting pattern. A low percentage value uses more color in the pattern, while a high value uses more of the image. The selected colors tint the image unless a blend value of 100% is set.

Bricks

Contrast (%)

Sets the color contrast between the two brick colors, establishing the dot-like variation within a brick

Brick Width/Height

Sets the brick width and height in real-world dimensions

Shift (%)

Sets the horizontal offset between rows of bricks

Half Brick Row

Adds a row of half bricks at the specified row interval

Half Brick Shift (%)

For half-brick rows, sets the amount of horizontal shift

Gaps

Size

Sets the size of the mortar joint gap in real-world dimensions

Noise (%)

Specifies the wobbliness of the mortar joints

Alt Bricks

Row

Adds a row of alternate brick colors at the specified row interval

Column

Adds a column of alternate brick colors at the specified column interval. Row must be greater than 0 to show columns.

Grass

Depending on the grass Density and the size of the model, using a grass shader on large surfaces can add significantly to the required render time. For large areas, using only an image shader rather than the grass shader is recommended, or break up the model into a foreground area with grass, and a background area with an image texture or color but no grass shader.

Custom Renderworks and Renderworks styles have an option to deselect Grass, controlling when blades of grass are depicted. Then, only the ground color or ground image is shown, without rendering grass blades. Grass is always off for Fast Renderworks and always on for Final Quality Renderworks.

Colors

The first color box specifies a color for the grass blade base and the ground, when an image is not used. The second color sets the color of the grass blade up to its tip.

Choose Image

Select an image to use for the grass as well as the ground between the blades of grass

Delete Image

Removes the selected image from the shader and uses only colors to create the grass

Image Blend (%)

When an image is used, specifies the blending between the image and the colors selected, to enhance the randomization of the resulting pattern. A low percentage value uses more color in the pattern, while a high value uses more of the image. The selected colors tint the image unless a blend value of 100% is set.

Length

Determines the length of each blade of grass

Width

Sets the width of the grass blades at the base. Each blade tapers to a point at its tip with a width of zero.

Density (%)

Specifies the grass blade density

Crinkle (%)

Specifies the curliness of the blades

Bend (%)

Curves the blades sideways

Wetness (%)

Makes the blades look shiny/wet

Noise

Pattern

Select the type of noise pattern to use. The preview helps distinguish the differences among the patterns. A generic noise pattern to select is Turbulence. Cell Voronoi is useful for creating speckled noise (set Low and High Clip around 70% each).

An example of each pattern is shown using default values for a color shader on a sphere with warm lighting on the top and cool lighting on the bottom. For comparison, this sphere has no texture applied:

The pattern might look different on a plane as opposed to the sphere used for the example. In addition, the appearance of each pattern can be dramatically affected by changes to its parameters. This example shows three variations of the blistered turbulence pattern.

Pattern

Varying only the Low Clip and High Clip percentages can completely change the appearance of the pattern.

The selected shader type also obviously affects the appearance of the pattern. This example shows the blistered turbulence pattern as a color shader and as a bump shader.

Metallic

Creates metallic effects (also try colored mirror shaders for polished metal effects). Metallic shaders usually look best with a dark Color shader combination.

If a legacy Preset metal is selected, metallic effects require the presence of light objects in the drawing; panoramic image Renderworks background lighting will not produce metallic effects.

Preset

Select a metal

Color

If Preset is None or a legacy metal, click the color box to select the metallic color

Color

Specifies a color to be applied as a transparency

Color

Click the color box to select the transparency color

Brightness (%)

Lightens or darkens the selected color

Glass

When using glass transparency, set the accompanying color shader to a dark color (or even black) for best results.

See the video link below.

Transmission (%)

Sets how much light passes through the glass; set to a high value when the glass is very clear

Index of Refraction

As light moves through a medium, the index measures the change in the direction of the light’s rays. An index of 1.0 indicates no change; a typical value for water and ice is 1.3, and for glass use 1.5–1.6.

To save time, use a value of 1.0x (just above 1) when the glass is thin.

Color

Click the color box to select the color that appears in a very thin object; for glass, this is usually set to white

Blurriness (%)

Blurs the transparency by the specified amount, or set to 0 for no blur. Blurred glass appears frosted (and takes longer to render).

Absorption Color

Click the color box to select the color that a large, thick object assumes, when a ray of light has traveled the Absorption Distance

Absorption Distance

Defines the distance rays of light have to travel before Absorption Color replaces Color. The lower the value, the more intense the Absorption Color is. This applies to thick or thin glass.

Plain

Provides plain, uniform transparency of a specified amount

Opacity (%)

Sets how opaque the shader is; set to a lower value for more transparency and to a higher value for more opacity

Rectangular Mask

Uses the texture as a rectangular mask to apply as a transparent texture (usually combined with another shader to create a specific masking effect). Useful for decals.

Horizontal/Vertical Repetitions

Indicates how to display the mask: a single instance, infinite repetitions, or a set number of repetitions in each direction

Shadow Catcher

Catches shadows and/or reflections that fall onto the object the shadow catcher is applied to in the alpha channel, so they show on an invisible ground plane. Rendered images with the shadow catcher can be composited with a rendered or photographic image file that has the alpha channel enabled to produce realistic shadows and reflections.

Objects that have a shadow catcher texture render black in Vectorworks, but everything other than the shadow/reflection is transparent in the composited image.

The shadow catcher cannot be used when rendering with a visible Renderworks background in a viewport. Shadow catcher textures can be used in design layers with a visible Renderworks background. See the video link below.

Catch Shadows

Captures shadows of rendered objects; deselect to show only reflections

Shadow Strength (%)

Controls the transparency of the shadows; lower values are recommended for more realistic shadows (0 shows no shadow and 100 is opaque)

Shadow Color

Specifies the color of the shadow; for daylight scenes, a dark blue is recommended for more realistic shadows

Uniform Shadow Strength

Sets all shadows the same color/intensity regardless of light source; deselect if multiple light sources are used, for more realistic shadows

Reflection Strength (%)

Controls the intensity of the reflections included in the alpha channel; 0 shows no reflections

Tiles

Many of these parameters are the same as for Color shader parameters; additional bump-specific parameters follow

Parallax Offset (%)

Sets the amplitude of the parallax mapping. Positive and negative values can be entered.

Parallax mapping enhances bump mapping by giving textures such as bricks more apparent depth, without the performance slowdown that can be associated with displacement mapping. Unlike displacement mapping, parallax mapping appears flat in silhouette.

Displacement Mapping

For realistic bump textures, displacement mapping creates texture and bumpy details with a rendering technique that appears embossed, projecting the geometry outward from the surface.

This mapping applies only to Final Quality Renderworks and Custom Renderworks when Displacement Mapping is enabled in the render options. Rendering can be significantly slower with displacement mapping.

If an image bump does not provide the desired results, try a noise bump shader.

Height

Specify a non-zero height to enable displacement mapping; large height values may result in longer render times

Detail

Sets the level of detail for displacement mapping; requirements and results vary depending on the texture and the surface’s face size. Textures without too much bump detail and a large face size, such as boards or stones, render with less detail and can be set with a lower level of detail; fine, faceted textures like grass or leaves may require a high level of detail, which also requires more rendering time. Conversely, very large surfaces, like a ground plane, may need higher levels of detail to see the displacement.

Self-Shadowing

Adds shadows to the displaced geometry, increasing realism as well as rendering time
