Light Groups

Hello people,
I’ve discovered that Blender used to have light groups (so they could affect some objects and not others), and it happens that this function is gone! Does somebody know what happened?
This feature is really awesome and I think all the other 3D softwares have it!
Is there a way of producing this result currently?

Blender used to have

it is render engine’s feature and it was in Internal (“Blender Render”).

There are built in: Cycles and EEVEE whose unfortunately currently does not have light groups.

Cycles light groups are being developed.

If You need it now you can:
Use some external render endinge eg. luxcore:
Or download custom build with experimental light groups:
