It adds that precomputation phase, and then one starts seeing the image progressively refining until it gets to the desired quality. This reduces render times by a significant percentage and works in a way that is pretty Secondary engine, which will activate the precomputation power of Corona.

Lighting gives an unbiased result (in a similar way to Maxwell, Octane Options: using the pathtracing engine for direct and indirect The renderer provides both unbiased and biased rendering Also, reduced flexibility and hardware limitations are the reasons why we do not want to go GPU way.” According to the developers “the reason is that our CPU version is fast enough, and there would not be nearly enough speed improvement to justify the amount of changes required. As stated earlier, it isĬPU-based (not GPU).

Unbiased vs BiasedĬorona takes advantage of the latest Embree technology by Intel to provide fast rendering speeds. After nearly 6 years of alpha development and the recent official release we can now put Corona to the test and compare it to other renderers.ĭoes it live up to the high standards of today’s render engines? Let’s find out. Other people got involved in the project, Adam Hotovy and Jaroslav Krivanek, and the team has kept expanding as the renderer continues to grow in popularity. What makes this renderer special is that back in 2009, during the rising wave of GPU renderers’ hype, there was a programmer called Ondrej Karlík who thought that CPUs still had a lot to offer, and that there was no real need to migrate to GPUs to get powerful (un)biased renders.Ĭorona started as a student project and evolved with time.

The quality of its renders and ease of use brought many early adopters, especially among Archivz artists. Corona is a render engine developed by Render Legion that saw its first official release in recent months.
