3Delight uses standard Maya's lights with the exception of the Environment Light which is 3Delight-specific (ambient light is not supported). To these standard Maya lights, 3Delight adds some additional controls (e.g. exposure, light focus, ...) in the 3Delight section of each light.
All lights share a set of common attributes to control exposure, diffuse contribution and specular contribution.
