In the Corona-3-c4d release from 01-2019
1) Instances of Corona Lights are ignoring the color
Corona Light, Instance, change Color in Light to red, Instance light will still render white.
2) Render Instances of Lights are working (including the correct color) in Interactive Rendering,
but they do not work at all (there is no Light) when rendering to the PV or VFB !
This has been reported here by illbru, and is tested by me, too.
