Rendering Heathering and Simple Texture Effects
You can use the technique described below to apply simple, uniform textures, such as heathering to objects in the image.
An example of a heathered texture is the fabric typically used for sweatshirts. The technique described here is not suitable if the texture contains discernible patterns.
To Apply Simple, Smooth Textures:
- Determine the view resolution.To apply a texture, Image Authoring needs to know the size of the object you are authoring. If the scene is simple, for example, if it shows an apparel item laid out flat and photographed straight-on, Image Authoring can determine object sizes based on a common resolution for the view image. This view image resolution is determined by measuring or estimating the distance (in inches) between two arbitrary points in the scene (for example, the width of the shirt), and the distance in pixels between the corresponding points in the image and dividing the latter by the former value, to arrive at a resolution in pixels per inch.To determine the distance in pixels between the two points in the scene, you can use the Photoshop Measure tool, or a similar graphics editing tool.
- Set the view resolution before creating any objects in the scene.
- Create a flowline object and a matching mask for each item you plan to render with the heathering texture.You don't have to separate apparel items into multiple parts.
- Adjust the [Illumination Map] if necessary.
