Quote from: KristofDeHulsters on February 04, 2021, 12:37:21 PMHi there Jay, The reason this flickering occurs is because of the low sample count. Keyshot is rendering each image in the sequence with 100 samples and then the denoiser is each time applied to that image. Because some of these images need more than 100 samples to properly resolve (this is depending on the angle you are shooting at and the complexity of the material and scene) the denoiser just blends whatever is there at 100 samples. What I would recommend is try to look for the image in the sequence that looks the worst, render that out to a sample count that you are happy with and use that sample count for the entire animation. You might also want to look in reducing the amount the denoiser affects your image if that is possible.Hope it helps!

None of them does a good job in animations!What KristofDeHulsters said is definetly correct: 100 samples is not enough! You might get away with a bit higher count and a decent Denoiser in After Effects. But I suggest to buy a Denoiser Plugin for AE. The free ones are mostly a waste of time in my eyes!I use NEAT Video and this Plugin does a really good job!If you don´t want to spend money, you have to crank up the samples and may have to play around with the lighting, but the blotchiness might by a hard task to solve...Search for "Blotchy walls" or similiar in the forum, you will find a ton of related posts...cheers designgestalt
