I am finding that the denoiser (at end) is working fine sometimes and others not. I rendered for an hour at low resolution and I had a very nice denoised png file at the end of it. I render the high res version (from Studio) with the same settings, albeit with a different name for the denoised image and located in another folder. After nearly 10 hours of rendering to SL12, I have no denoised png file.
So, checking the console, there is a Denoiser error: Error running denoise process: OpenCL exception. Why would this be when I run an Nvidia Titan Black gpu? Shouldn't it be using CUDA as after all the Denoiser was set to use GPU? I'm not sure the GPU ran out of memory because the final file was 4500x3000pixels and I have successfully had a denoised image at this resolution before. I have just installed the OpenCL runtime for intel cpus to see if that will help and seems like a couple of test renders to SL6 at 1200x800 on CPU Denoiser worked fine. I do not have time to try again at the higher resolution however.
It seems I can recover the tmp files for each pass from my user temp directory, so I have copied and pasted those to another folder, but I am having no luck following the command line instructions using mximerge. I am getting an error "Cannot read/write specified files" although they each open fine in Maxwell Render and I have tried running cmd.exe as administrator. Any ideas?
