https://corona-renderer.com/ By far the best IMO. Its free, development is very active and it has a unique blend of unbiased/biased rendering system. For Max only at the moment though.
so from my understanding. physically (unbiased) rendering engines generally are a bit easier to operate ? since its rendering is based off of calculated light pathing - though it gives the user less control compared to the biased engines... and in general, takes longer to render a product. while the biased engines allows…
You know unbiased engines take a looooooong time to render, right? Such is not practical for animations unless you have a render farm to back up the job. Maxwell Renderer is, theoretically, the most "accurate" unbiased engine out there. It is more or less designed to simulate the physics behind an IRL camera. V-Ray has a…
