Long Render Time & Problem Adding Outdoor Scene

Hi All,
I'm a self-taught SketchUp & Twilight user, as part of completing an interior design course. I've hit a stumbling block with one of my designs...I've done 'something' to mess up my model whilst trying to add a street scene outside the window (which failed) and now my render times are ridiculous (2 hours on the 'low' setting). I've deleted the photo that I turned into an emitter outside the window and also tried to restore the Twilight environment back to 'physical sky'...with no improvement to said render time. Argh.
Please can someone remind me what the Twilight environment default is and also give some ideas what else could be slowing down a render that used to be fast (I don't believe I've changed anything else)?
Also a simple guide to adding a street scene outside the window, that can be seen through a rendered glass window (a single pane of architectural common glass)? I tried to watch the Twilight tutorial on creating spherical sky etc, but I'm not sure if it's too complex just for an interior design that involves 2 windows.
Help! Thanks in advance.
Sarah

For the emitter plane of street scene, set it to "Fake Emit" and it will add NO render time. Do this will
all emitter surfaces. Emitter surfaces are best with Easy 09 interior render setting. Easy 1-7 render settings it is better to use points and spot lights.
For restoring default sky use this button and choose "Default".
See also my tips in this recent thread when someone had a similar problem.

Hi Fletch,
Thank you very much for this advice. It turns out I'd already set the environment back to default, but I did need to make my scene outside the windows a 'fake' emitter. I also exploded my windows and it turns out there was an additional pane of glass in there, so after removing that, I could see the outdoor image after rendering. Duh.
The slow render time seems to have improved now I've removed an LED emitter strip I added underneath the kitchen units. I've now removed this to save time, but for my reference in future, would another type of Twilight lighting also create a realistic LED Strip? Or should I stick with using emitters and use render setting 9? Thanks.

I have same issue,any other proper solution?
A chart template is a pre-designed framework used to display data visually, typically in the form of graphs, pie charts, bar charts, line charts, or other graphical representations. Blood sugar chart templates typically include columns or sections for dates, times of the day, blood sugar readings, and any notes or observations related to factors that may affect blood sugar levels, such as meals, medication, exercise, or stress.

Alex, what does "proper solution" mean?
The solution is clearly and carefully explained above.
