Corona Sun Direction [Bug]

Corona Corona for Cinema 4D Corona for C4D :: Issues
1
  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 ?

Can confirm.

the sun controls/changes its own rotation and there seems to be a bug when it is nested in a hierarchy.
it would be nice to have a switch to turn this off and have it work like a regular light
