Clouds not showing

Hi,

Reproducible likes this:

- Create VraySun
- SunSky in Environment
- Specify Sun node in VraySky

In short when a sun is specified in the VraySky map, the clouds are not showing. Only when the box is not ticked, it works.

The clouds’ aren’t yet implemented in the sky map itself (the clue is the lack of clouds’ controls in it).
It’s on the to-do list, though.

Noted, I thought the clouds were part of the sun system not the sky map, since it’s a different drop down menu.

We could rationalise the UI a bit, agreeably.
