Preparing High-Quality Textures in Vectorworks for Export to Vision 2021

In Vectorworks, textures are composed of “shaders” that control color, reflectivity, transparency, and surface details like bumps and indentations. The shader settings include default options such as Brick, Plastic, and Cloth, or the option to use image files. Vision works best when images are provided that match the size and complexity of the textured objects.

This workflow describes the image requirements and shader settings in Vectorworks that result in high-quality textures in Vision. Several of the shader settings in Vectorworks do not apply to Vision; only the useful settings are described below.

Vision’s default texture resembles a non-reflective gray plastic. Special tips are provided for creating metallic textures that clearly reflect the surrounding scene.

Getting Started

  1. From the Resource Manager, do one of the following to open the Edit Texture dialog box. For an overview of the parameters, see “Creating a new texture” in the Vectorworks help.
    • To create a texture, click New Resource. Select Renderworks Texture, and then click Create.
    • To edit an existing texture, right-click on the texture resource, and select Edit from the context menu.
  2. If you’re editing an existing texture, remove any shaders that do not use image files. For example, de-select Metallic, Glass, or Noise if these options were specified for the Color, Reflectivity, Transparency, or Bump shaders.
    • Initially, removing these shaders will make the texture look less realistic. The following steps will add high-quality details.

  3. When using image-based shaders, select images with sufficient quality. The optimal resolution depends on the size and detail requirements of the textured object.
    • For example, a guitar string may only require a 1x1 resolution Reflectivity image, whereas a mountain may require a 4096x4096 Color image for adequate detail. Typically, a resolution of 256x256 or 512x512 is sufficient.

  4. If the texture has just one color, set the Color shader to the desired Color (this is an exception to the image-based workflow). An image-based shader should only be used to provide multiple colors and more detail.
    • To create a metal texture, use a full black (0,0,0) Color shader. Do one of the following to specify the black shader:
      • Set the shader to Obj Attributes and specify a black fill color for the object.
      • Set the shader to Color and select the black Color from the Edit Color Shader dialog box.

  5. All Reflectivity shaders should be set to Image. Brighter images reflect more light.
    • Non-metal textures should use grayscale images.
    • Metal textures should use colored images that match the metal’s color.
      • For simple objects with a single color and no fine details, use a small-resolution image. For example, use a 1x1 silver image for a guitar string.
      • For complex objects with multiple colors, use larger, more detailed images. For example, use a 512x512 gold Reflectivity image for a glittering set piece.

  6. The blurriness of a reflectivity image determines how blurry or sharp the reflection appears. To set the blurriness, click Edit next to the Reflectivity dropdown in the Edit Texture dialog box. The Edit Image Reflectivity dialog box opens; enter the Blurriness percentage. Lower values create sharper specular highlights and more mirror-like reflections of the object’s environment.
    • Enter lower values for smooth and shiny metals or plastics. Enter higher values for carpeting, rough plastic, or dull metals.

Tips for Best Performance

  1. To add detail without slowing the program, apply a Transparency shader or Bump shader to a low-polygon extrude instead of using a complex mesh object.
    • Transparency shaders should use black and white images with no gray. White will be rendered and black will not.
      • For example, create a chain link fence by applying a Transparency shader to indicate the gaps.

    • Bump shaders should use grayscale images. Black represents the elevated, or “bumped,” areas and gray shows the indentations. Lighter shades of gray look more indented.
      • For example, a brick texture should use black for the bricks and gray for the sunken mortar.

Verifying Texture Quality in Vision

  1. Export the scene as a .mvr file, then change the extension to .zip, and extract the contents.

  2. Check the quality of all exported images. In Vectorworks, replace any images that don’t meet the requirements described above.

  3. Import the .mvr file in Vision.

  4. Add lighting and environmental features for more realistic renderings. In the Document Preferences, specify a Background Color or Panoramic Background for the scene, and then experiment with the Sun Azimuth and Elevation settings and the Ambient Color.

  5. In the Vision Preferences, set the Texture Quality to Very High.

  6. Do the following in the Document Preferences:

    • Select Render Specular to check the specular reflectivity. Metallic objects should use the metal’s color.
      • White indicates high reflectivity.
      • Black indicates no reflectivity.
      • Gray indicates low reflectivity.
      • Color indicates metal reflectivity.

    • Select Render Normals to check the bump and indentation effects. Verify that the protruding or indented geometry is facing the right direction:
      • Red indicates left-facing normals.
      • Green indicates top-facing normals.
      • Blue indicates front-facing normals.

  7. On the Properties palette, check the Specular Power for various textures. This value depends on the Blurriness setting in Vectorworks.

    • High blurriness results in low specular power, and vice versa. This means that rough and dull textures will not have bright highlights or clearly reflect the environment.
    Blurriness Specular Power
    100% 1.0
    80% 4.0
    50% 32.0
    20% 256.0
    0% 1024.0

  8. If the color of a metal texture does not look right, try lowering the Blurriness value in Vectorworks.

  9. Turn up the Ambient Intensity with the Document Preference or keyboard shortcuts. Navigate the scene to verify that textures look right in full ambient lighting.
