I have been using 3D software and the many available rendering tools, plug-ins and native engines since the mid 90's. They have changed drastically over the years with the latest options being incredibly efficient and providing amazing image quality. Their methods of creating a rendered scene are usually quite different and the work flow for each is unique enough that you either hate it, love it, or tolerate it because of need rather than want.
With Corona Renderer there are several benefits that make it easy to love the software. The work flow is simple, fast and doesn't require a great deal of self-education to understand. You can, for example, easily use the native materials in 3D Studio Max for a fast render that can actually be used for a final image for post editing. But to use the small number of native Corona materials and maps (compared to 3DS Max) will allow you to create incredibly realistic images so very easily.
Another of the benefits is speed. Oh my, this renderer is fast. With my I5-3570k, AMD R9 290 based machine I can have a usable render of a 1920x image in minutes. Most other software can take several minutes to get started and a similar quality image to Corona can easily take twice as long. Test renders can be done in seconds versus minutes with others software and the quality is amazing. Review collected by and hosted on G2.com.
