Hi Paul,
1 - in daylight environment I can only modify the power of sun and sky together. It would be very useful if power of the sun and power of the sky were two distinct parameter.
2 - It would be useful to have direct light to use in place of the sun because, if I use sun with low altitude, sun color is reddish and its power decrease. Furthemore, if there was direct light, it could be used with hdri light (for example, a direct light in combination with a cloudy hdri to better control the light of the scene)
thanx a lot
