How to reduce the noise<\/strong> in your Daz3D Iray renders? This Daz3d Denoiser question comes to mind to almost anybody who uses Daz Studio. Because everybody sometimes has a problem with noise<\/strong> in their renders.<\/p>\n\n\n\n There tends to be a lot of noise on some renders, while others look perfectly good at 100 samples or even less. Why is that? How to improve<\/strong> on this? How to use Daz3D denoiser?<\/strong> All this will be talked about further into the article.<\/p>\n\n\n\n Source Moriah the Conjurer Bundle<\/a><\/span><\/p>\n\n\n\n First of all, to fix the noise problem we need to understand how and why it appears<\/strong> at all. Without understanding we can\u2019t do anything. And the main reason for noise<\/strong> is the lighting of the scene.<\/p>\n\n\n\n Lighting in general is what a big part of rendering time and computer powers goes to. Calculating where light goes, how it reacts with different surfaces and how it jumps around is not easy even for a computer<\/strong>.<\/p>\n\n\n\n Okay, so if lighting is the reason for the noise – how exactly does that work<\/strong>? When you first think about it, the answer would probably be, that the more complex lighting your scene has – more noise there will be. But this is not exactly true, it depends more on the differences of lighting<\/strong>. Complex scenes can have less noise overall than simple ones. How? We will look into this more in the next section.\u00a0<\/p>\n\n\n\n Source Frogol HD for Bullwarg<\/a><\/span><\/p>\n\n\n\n Very simple way of reducing noise<\/strong> on the scene, that some people simply forget about or even don\u2019t think of – is to optimise the scene overall. Simple way of doing this is considering what parts of your scene you don\u2019t need<\/strong> and deleting them.<\/p>\n\n\n\n Maybe there are too many light sources? Or you have a bunch of objects that are out of your render view? You should get rid of them<\/strong>. Even if something is not in the render directly – it can affect it. <\/p>\n\n\n\n Consider using the Scene Optimizer<\/a> product. It can really help with optimizations<\/strong> and not only reduce rendering times, but also reduce the amount of noise you have in a scene.<\/p>\n\n\n\n Example of the tool effectiveness – source Scene Optimiser\u00a0<\/a><\/span><\/p>\n\n\n\n Probably most important – optimise the lighting of your scene<\/strong>. As was said previously lighting is the thing that affects noise the most. If something is far too bright or too dark – you will definitely have a lot of noise there unless you bump the samples numbers up a lot.<\/p>\n\n\n\n It is really bad<\/strong> noise-wise to have only one strong light on a scene. As this will create a huge difference between dark and bright<\/strong>, which definitely creates noise:<\/p>\n\n\n\n Noise can be seen in the darks here. Especially on the character’s chin and neck region. If I would just tune the lighting strength down a bit, render already will be much better. Noise is still there, but it is far less noticeable:<\/p>\n\n\n\n And you can go further by adding lights and HDRIs to make a proper lighting. <\/p>\n\n\n\n Alternatively, in a room render you could remove some unseen walls and ceilings to let more light pass in and to get overall light from more angles. <\/p>\n\n\n\n Though, note that going overboard with lighting sources is not a good idea<\/strong> either. As this can lead to a situation where you will wash out the shadows<\/strong> and thus details of your render. Or this even can have a negative outcome on colors of a scene – so use always with care.<\/p>\n\n\n\n If you would like to learn how to create proper lighting setups<\/strong> that both don\u2019t have too much lights but have enough to get rid of all the black shadows – read our Daz3d Iray Lighting Tutorial<\/a> that explains everything.<\/p>\n\n\n\n<\/figure><\/div>\n\n\n\n
