Rhino Toucan lights turned off

All of a sudden any lights created in Rhino Toucan won’t stay ON. The settings are not saved and and the light is turned off automatically.

Played with all the render settings, no dice.
Quit, relaunch. Nothing.
Restart Mac. Nothing.

Any fix ?

Hello - do you mean the lights go off between sessions (save and close the file, reopen the file) or right away?
Any kind of light? So far it works here…


The lights are created OFF. Make some adjustments. Click off in the ether. Render and come back to a light that is OFF and has lost all it’s settings. Does it for all types.
