Hello, I'm using Corona Renderer and I've set the noise level limit to 2% and the denoising mode to Corona High Quality. However, my renders are taking an extremely long time. For a small bathroom render, it's estimating a render time of over 6 hours. What could be causing this? My polygon count is reaching 2,000,000. Could the objects I've included, even if I've deleted them later, be affecting this? What steps should I take?😪
Highly reflective surfaces, opacity materials, some lights and refractive materials takes longer time to render.. so that might be the cause of your issue
@@manishpaul2760 I appreciate your feedback. I've developed a new model, optimizing it with a proxy and reducing the object count. Despite these optimizations, I anticipate a render time of approximately 7-8 hours for my scene containing 120,000 polygons. The scene is illuminated solely by sunlight and includes only reflective surfaces on mirror and fixtures.

Hello! I have a question, my render is not high resolution even if I do same settings and I select 3080x2160 pixels. How can I make it look detailed as much as yours?
No it is not the same for me, but that depends on the Specification of your Machine, if it isn’t so high, I recommend you reduce the number in your aspect ratio so instead of rendering out 4k images you should try out Full HD, still sharp, maybe not as sharp as 4k but it works too
Hi I'm a Pc builder gathering info to build a pc for an architect haha. I wanted to know with the Corona High Quality while looking in the performance tab in Task manager, does this mode pushes GPU or CPU or fully use both at the same time?
Corona is entirely CPU-based (with optional GPU denoising which requires a compatible NVIDIA GPU). So to answer your question, it pushes more CPU, the only time gpu gets used intensively is during denoising while doing interactive rendering (Nvidia GPU AI) other than that, CPU all the way.
@@SimpleorDifficult Thank you very much. Do you know if it's single core dependant or multi core? Most software apparently don't utilize all the cores effectively.
