Twilight Render User Forum

I want to do a WC rendering only with interior lights, without sun shadows, but when I do this the interior becames almost black, even with the lights I put on.
Any tip for the best parameters to do so?
Thank you
(I'm a begginer on this: I work with Sketchup Pro 2020 + Free Twilight render)

Here's the tutorial with a kitchen, but the same principles apply for any interior space.
