3Delight
...
for Maya supports Maya's
...
standard lights. There are three exceptions: the Environment Light
...
is 3Delight-specific
...
and the ambient light
...
and volume light are not supported
...
. To these standard Maya lights, 3Delight for Maya adds some additional controls (e.g. exposure, light focus, ...) in the 3Delight section of each light.
...
Common Attributes
All lights share a set of common attributes to control exposure, diffuse contribution and specular contribution.
Common 3Delight-specific attributes for all Maya lights.
Exposure
This is an additional control over standard light's intensity. Exposure is in many cases the a preferred control due to it's likeness to photography. Final area light intensity is then computed:
I = intensity * pow(2, exposure)
Diffuse Contribution
Attenuates light source intensity for diffuse rays.
Specular Contribution

3Delight's Unified Sampling
You will notice that there are no sampling parameters for light sources in 3Delight for Maya. 3Delight's unique Unified Sampling algorithm simplifies greatly the control of noise in the image by providing a single parameter in the Render Settings that acts on all shading components, including lights.
