In this tutorial we will talk about denoiser tool in vray for Revit. To remove noise in the final render, just follow the tutorial. To activate it, go to the setting section and activate it in the channels section. The most important part is choosing the engine of this tool. If you use nvidia geforce graphics cards, you can choose this option because it is faster. The first mode is the default and the third mode is to use the CPU for calculations. When the rendering process starts, the noise gradually decreases, but in the end, some noise remains. Now we wait until the rendering time passes so that the noise decreases. As you can see, the effect of the denoiser tool is very clear. The denoiser tool removes the noises by combining the surrounding pixels, so the scene should not have a lot of noise, because applying the denoiser on such a noisy renderer will not give good results. The opacity option determines the effect of the denoiser tool on the rendering.
