LightGen - "Generate Variants" button disabled

When I open the LightGen window, no matter what settings I choose, the Generate Variants button remains disabled. I’ve not activated LightGen previously in this model but have done it successfully in other models in the past. Am I doing something wrong or missing a step? I don’t do any specific prep before opening LightGen.

Hello @daly_mather ,

Are you trying to Generate Light Gen scenarios while Interactive render is enabled perhaps? If yes, please note that Light Gen cannot be generated during render.
You can also hover your mouse over the button to see a message that appears.

Let us know if this was the issue.

Hi Natalia,

That was it--I feel silly now, thank you.

Thank you @daly_mather for confirming that it was the reason!

Glad that everything works now, please do not hesitate to contact us should you have any questions.
