Reality sun with meshlight

[EA3D]

Dear Paolo, friends!

Have an exterior scene with Reality sunlight only (sun + sky IBL). Because of some shadows on the foreground I decided to add one meshlight. At a first look it seemed that the light is not working at all. But when I tried to add gain I noticed that it's needed to have more than x5000 gain to see the influence of this light to the scene lighting. I've never seen such a behavior, usually 1-3 gain is enough for adjusting.

Is it a feature or a bug? Any special instructions for using sunlight together with other lights?

Is your kernel in lux set to auto linear? If so switch it to linear or turn on exposure settings for your camera in reality.

No-no, it's set to linear with fixed exposure.

Sun and sky is pretty strong creating deep shadows, so it would not be unusual that you would need a lot of gain on a normal mesh light to get any effect in your scene. Standard power is 100 Watt (efficiency of 17%). For a bright sunlight outdoor scene, such a light would not have a huge effect, especially if diffused, which mesh lights typically will be.
