Path tracer noise

Hi everyone! How to reduce noise without denoiser. I use higher parameters of samples than education videos. But result much worse. Denoiser result is so bad and without denoiser cant normally reduce it in DaVinci



If you don’t use the denoiser, you will need to highly increase your number of samples.

Hi. In my case, increasing Samples Per Pixel, doesn´t change anything. The amount of noise is the same. I used 4096, and it´s exactly the same result.
How to increase quality without use Denoiser? Because, denoiser, usually changes the details…

same problem for me… i used 16000 samples and the result is the same when i use 4096!!! did you find a solution???
