For kicks I decided to recreate the solar eclipse situation and it looks wrong - I’m supposed to get a dark moon ball in front of sun (see attached pic from wiki) but currently it just sky.. I guess its from the Vray department, hope they will improve it promptly.
The wording is misleading. The PRG sky model does not support solar eclipse currently. The fix is just for the order of the two discs, but there is no sky darkening, corona, etc.
implementation of corona should be done in Prague - this is principal lol
