1) Add a Corona Sun "Sun1" with Rotation 120 ° and Angle 35
2) Add a null with Rotation H = 45
3) Copy Sun1 as child under null, name it "Sun2"
4) change the Sun2 Rotation 75 ° in the Attribute Manager (in the Rotation and Direction section)
Both Suns now have the same Z Vector, but.... the sunlights come from different directions !
Also the GUI display is wrong.. the "Star" is at the opposite end of the Z vector,
but the white sun angle indicator has a different rotation.
When u change the "Rotation" back to 120 from 75 you dont get back the previous state,
both the direction and the Z Vector change but do not match as before.
Second Issue:
if you now change the rotation of the null, the sunlight direction of Sun2 does not change.
this is all highly confusing as it contradicts core concepts of c4d ...
the sun seems to tamper with its rotation and doesn't use its Z direction (as any other light in c4d)
i could understand if the "Rotation" and "Angle" would be global/absolute Values, but they aren't
best, index
ps.
sometimes it makes sense to have different lightning setups grouped under a null
there might be a composition with a sun and other lights and scene elements
just rotating the null to adjust the direction doesn't work atm.
pps.
btw ... how are rotations of sun and sky connected ?
does it matter if the sun and sky object have different rot.H values ?
