You can find a description of common light parameters on the lights page
. Additional attributes are described below.

 

Resolution

The resolution attribute should be used with care. The higher the resolution value, the longer the skydome_light will take to precompute the importance map for that light. For high-resolution maps this can be very slow.

Format

Portal Mode

 

Flip

Enable this option if you want a matching result with the Cinema 4D Sky object which flips the texture compared to Arnold.

 

Visibility

Camera

Transmission

Diffuse / Specular / SSS / Volume

AOV Indirect

 

The skydome_light will not work with atmosphere_volume. You must use regular lights that have a precise location and size, and inverse-square decay.
