How long does it take to render? or Why does my render never finish?

Because it is an unbiased renderer, Indigo will not tell you when it thinks it is finished. It is up to you to decide when you think the render is clear enough for your purposes. Most renders will give their first image within 30 seconds, but it may take 3/4 hours to give a clear image. Large images (greater than 5 megapixels) may need to be left overnight to become clear.
