Render Elements Panel and Rollout Rendering menu/main toolbar > Render Setup > Render Setup dialog > Render Elements panel > Render Elements rollout This topic describes the available types of render elements and how to use them. These are the elements you can choose to render separately: ■ Alpha: A grayscale representation of the alpha channel, or transparency, of the scene. Transparent pixels appear in white (value=255) and opaque in black (value=0). Translucent pixels appear in gray. The darker the pixel, the more transparent it is. The alpha channel can be useful when you composite elements. ■ Atmosphere: The atmospheric effects in the rendering. ■ Background: The background of the scene. Other elements do not include the scene background. Include this element if you want to use the background in compositing. The background is not trimmed against geometry, so elements should be composited over the background. See Compositing Rendered Elements on page 6342. ■ Blend: A custom combination of the previous elements. The Blend element displays an additional Blend Element Parameters rollout on page 6355. ■ Diffuse: The diffuse component of the rendering. The Diffuse element displays an additional Diffuse Texture Element rollout on page 6370. ■ Hair and Fur: The component of the rendering created by the Hair and Fur modifier on page 1119. See Hair and Fur Render Element on page 6356. ■ Illuminance HDR Data: Generates an image containing 32-bit floating-point data that can be used for analyzing the amount of light that falls on a surface perpendicular to its normal. The illuminance data ignores material characteristics such as reflectance and transmittance. 6336 | Chapter 20 Rendering
