Nice BB,very excited about this

This exposure will works like IDL intensity or in different way?

Rotation of sun,if I add Infinite light can be this linked together ?

Thanks,Jura

The exposure is not IDL intensity. The exposure parameter is like adjusting the camera - let in more light or less light from the whole scene, both direct or indirect. Or it could be like the camera ISO - make the film more or less sensitive. That is the exposure dial - to adjust the exposure. It works by adjusting the brightness of ALL lights and ALL environment spheres, simultaneously, synchronized. IDL intensity is the multiplier used not only for response to glowing lights, but also to bounced light, so it is somewhat different in what it controls. IDL intensity does not adjust response to direct (sun) light - my "Exposure" dial does both. Note: I have IDL intensity fixed at .65 all the time, but I could easily expose a dial for this in the BB sIBL tool. I will add it. 

For the rotation of the sun, BB sIBL adds the infinite light, too, and makes it point where the sun is in the environment sphere, so they match. When you use the BB sIBL rotation dial, you're rotating the spheres and the infinite light, together, with one dial.

If you wish to have other lights, and rotate them as well, you just need to parent the additional lights to the sIBL sphere.

The Sun (infinite) light is actually parented to the sIBL sphere, so if you directly rotate the sphere, the light(s) will rotate, too. You do not have to use my rotation dial.

The reason I made a rotation dial is to make it always accessible and to control which direction is the sun when you load an sIBL before you even have a sphere or sun yet.
