we need this fixed I have 6 high res image sand 3 animations to render please
I attached a render I think it explains what is happening, I rendered this to CXR with gathering data fro denoising and denoised in corona image editor, it seems corona is not gathering the denoising data from render nodes.
Could you please file a bug report on Mantis? That way we're sure not to forget about this bug and you'll be informed about any progress. Also please save the data sent by DR slaves to master and attach it to the bug report. You can save the data by checking the "retain EXRs" checkbox in render setup DR rollout.
I am sorry but I don't have time to do this. This is not a bug that I should be fixing for you it is your software and your business. it is a major flaw, akin to Corona shooting itself in the foot, it is like a Trojan horse that Vray sneaked in, the code for the sampler is buggy enough to be unusable in production, and it prevents rollbacks.
The stratified sample is slower, but at 200 passes it is so much cleaner to a point where it barely needs denoising, while the new vray sampler is so dirty especially in corners. the time saving is 10 minutes or 15 minutes off 2hrs of rendering.
One of the main reasons I moved from Corona to Vray is the Corona had a predictable behavior. You start introducing approximations into it and it is no longer what we want. With Corona I can render animations with moving objects using path tracing with 40 passes and it will be cleaned by the denoiser and the only flickerign I have is with bloom and glare which i can turn off while with vray you need more time to render the same thing with brute force to remove the flickering.
And another thing is I myself have been looking for a partner for the last 20 years, with my wife telling me to play by myself it is safer, I looked everywhere and after 20 years she is right. Same with Corona you do not need Vray they will smile at you and stab you in the back believe me. I am older than you I have seen life you have been doing great so far on your own but now you invited the big grizzly bear into your cave.
