I have downloaded the latest build: how to activate OIDN?
Thank you,

unless your cpu is like, from 2004 or so... it should work I guess. (check if your cpu supports sse4.1)rickyx wrote: Mon Feb 11, 2019 9:31 pm Thank you, results are really amazing.
Just another question: the Intel OpenImageDenoise is optimized for Intel processors.
Will it work also on other processors (ex. Amd) or it is like Cuda for Gpu?
Works perfectly on my Ryzen 7, like 2s denoising time for full HD.rickyx wrote: Mon Feb 11, 2019 9:31 pmJust another question: the Intel OpenImageDenoise is optimized for Intel processors.

Usually, Intel Libraries like Embree and Oidn have different code paths optimized for various level of SSE/AVX/AVX512 support. Indeed they will run very well on top Intel hardware (i.e . AVX512) but they will work well on modern AMD CPUs too.rickyx wrote: Mon Feb 11, 2019 9:53 pm Ok, got it
I meant... I didn't know if it was related to specific intel hardware.
I'm lucky! I have an i7![]()
@Dade: Could this be implemented in LuxCore? I found that the noise from randomly sampled reflections/refractions on glass really throws the denoiser off, sometimes not denoising the affected area at all. It would be much better if the albedo was completely noise-free after the first sample.https://openimagedenoise.github.io/documentation.html wrote:The albedo for dielectric surfaces (e.g. glass) should be either 1 or, if the surface is perfect specular (i.e. has a delta BSDF), the Fresnel blend of the reflected and transmitted albedos (as previously discussed). The latter usually works better but only if it does not introduce too much additional noise due to random sampling. Thus we recommend to split the path into a reflected and a transmitted path at the first hit, and perhaps fall back to an albedo of 1 for subsequent dielectric hits, to avoid noise.
