Hello, I am new to luxcore and I wanted to render out caustics.
So I followed this tutorial, I switched my engine "Bidir", I used 250 samples which got me 9 minutes on my ryzen 7 3700, but I am having trouble with noise in dark areas of my scene. I have tried turning on 'denoiser' in the render properties and the denoise node in the compositor but its still pretty noisy.
Any help is appreciated

My bad! here you go. My scene is basically a plane with pbr texture, and an invisible sphere being deformed to create the caustics. I also forgot to mention the tutorial also asked me to switch to 'metropolis'.

Thanks, I that think did the trick. My render keeps crashing whenever I try using GPU, but I think that has something to do with my amd gpu.Sharlybg wrote: ↑Mon Feb 08, 2021 10:51 am You don't need Bidir i think.
