At the beginning there were only the approximate renderers where the global illumination is solved by means of inversion and interpolation. With machines becoming more powerful, unbiased renderers finally emerged in the commercial world. Unbiased rendering takes typically longer to finish since it really has to compute all amounts of lighting transfer with the benefit of more accurate results. Unbiased rendering has typically only a few parameters to tune making setup easier, but biased renderers have still the upper hand when it comes to animations.

Thea Render is the first commercial solution that contains both state-of-the-art biased and unbiased engines. This means that the advantages of both kinds are present in a unified framework. All render engines use the same materials and lights without any hidden obstacle between using one or the other. No need anymore to convert materials or parameters from an unbiased renderer to a biased one (and vice versa) because there is a job that one kind can do better.

Render quick high quality biased animations and astonishing unbiased stills. Or render astonishingly realistic unbiased animations and quick high quality stills. Let the full unbiased solution rendered or take more control over the lighting using the biased engine. The choice is yours and just one switch away.
