Since the second hotfix, I can’t use the denoiser. As you can see, I get dark boxes that do not recover. My whole scene was dark when I enabled the denoiser, but the scene would quickly brighten. Now, nope, just dark buckets.
Could you simplify the scene and send it to support@chaosgroup.com (or attach it here) so we can take a look? Mention this thread in the e-mail along with your V-Ray and host platform versions and a V-Ray log.
