vray ies lights settings not working

[woongeluk]

Vray 4 and sketchup 2020: I have two rectangle lights in the model and added two ies lights. These ies lights cannot be changed in intensity, for when changing the intensity of an ies light the first rectangle light in the list gets changed. The menu under the preview does not change when one selects another lightsource. The ies lights are bsically off because of this. Is this a bug or am I missing something?

Hello, and apologies for the delayed reply!
IES lights can have their intensity value modified. By default the value from the .ies file is read but if the "intensity" parameter checkbox is enabled a custom value can be specified:

The fact that a rectangle light's intensty is changed when actually modifying another light sounds like a bug.
Could you please confirm whether this is reproducible only with a specific scene? A step-by-step description or a video capture of the actions you take will also help us determine what may be causing this behavior.

Kind regards,
Peter
