| - | Rays: This slider is used to determine the number of samples in a discrete evaluation of the integral across the half sphere for diffuse outgoing radiance with a constant radiance field, with a minimum of 256 and maximum of 8192 rays being available. A higher number or rays will increase the quality of the Transmission at the cost of speed. We do not recommend going below a value of 512 rays as this can cause banding to appear in the map. A value of 1024-2048 or above should be perfect for production. | + | **Rays:** This slider is used to determine the number of samples in a discrete evaluation of the integral across the half sphere for diffuse outgoing radiance with a constant radiance field, with a minimum of 256 and maximum of 8192 rays being available. |
