HDRI lighting

HDRI lighting is node combine DOME LIGHT and Environment. It creates both nodes under one transform. You can also do it manually.

For FAST and EFFICIENT HDRI lighting in most cases combine DOME LIGHT with Environment.

What is different between lighting by DOME LIGHT and Environment only?

Dome Light use image analyze for HDRI map. It means faster and less noisy render for HDRI map with big differences between bright and dark pixels in the map. The HDRI texture will be converted into hundreds light internally.

Environment lighting only, without Dome light and Environment with specular and diffuse weight 1, is better when you use HDRI map with low variance and blurred. Your Indirect diffuse and Specular has to be turned on.

• TIP - You can use the same or different texture in Environment and Dome light.
• You can also combine more Environment maps and more Dome lights.
• You can set different textures and weights for each parameter (Background, Diffuse...)

 Just DOME LIGHT with HDRI map is enable                                                  DOME LIGHT and Environment with HDRI map is enable

• TIP - When you use DOME LIGHT with Environment be sure your specular and diffuse weight are set to 0 in Environment (Default setup)
• Otherwise you will double this parameters, because there are turn on on Dome light
