Render channel

Outputs the main render image. You can choose between six options in the Render type combo:  

• All: The usual complete render. Output the whole render including diffuse, reflections and refractions.
• Diffuse: Output an image containing only the diffuse color of the surfaces.
• Reflections: Output an image containing only the reflective component of the surfaces.
• Refractions: Output an image containing only the refractive component of the surfaces.
• Diffuse+Reflections: Output the whole render including both diffuse and reflection components together.
• Reflections+Refractions: Output an image containing the reflection and refraction components together.

Separately rendering the diffuse and reflective components allows for greater flexibility when compositing.
