Twilight Render User Forum

Good evening, how come even though I set shadows during rendering you see everything dark? but if I remove the apartment's ceiling is better, thanks

Be sure all windows are only modeled with a single pane of glass.
Be sure you have applied a material to the glass using SketchUp's materials, such as the typical "translucent_glass_grey" or whatever
Be sure you use the Twilight Material Tool to click that glass material on the windows and apply the Architectural Glass>"Common" or "No Shadow" set glass material color to white and alpha to Zero.
Please follow Video Tutorials.

Also, note that the 'Shadows' option is ignored when rendering with Interior / Interior+. Shadows are always on for this render method.

Maybe that not what you wanted but this is actually a really nice render
