The best part about this software is that it allows me to design renders in such an efficient manner for my projects. I cannot imagine working with another lighting tool, at least not in comparison to Indigo Renderer. It's very fast as well. It works great on my Mac OS X 10.7 computer but sometimes freezes when using Windows 7 (especially if I'm doing several things simultaneously). Sometimes, the program crashes unexpectedly after rendering or exporting images. Otherwise, everything has been excellent so far! As many other users have mentioned before me, there may be some additional features we would like to see included in future updates. My favorite feature includes its speed and ability to work through multiple files quickly without getting slowed down by the time lag between loading each file into the application. I am also able to save render times to my desktop folder and load them.
