In this Daz Tutorial we look at how to remove fireflies from your renders. Fireflies are small little anomalies, something different than noise or grain within daz 3d, that can appear in certain circumstances such as low light conditions and from reflections.
In this daz 3d tutorial video we take a look at how we can remove fireflies when the usual "Fireflies Filter Enable" doesn't seem to do the job and instead we need to use the Noise Degrain Filter instead.

Thanks Rauko, the firefly problem was becoming a real pain. Great video and solved by moving the slider to the right.

@jimjak6947 4 месяца назад

Thanks for making this man, great tutorial. This is the same issue I am having with "Post Denoiser". Getting fireflies from shine on the models hair and nails. I can remove it by just enabling post denoiser but it softens the image just like this did. I remember this issue in 3ds max years ago...I just think the render engine in Daz is still behind, but overall amazing program.

@RaukoDaz3D 4 месяца назад

Sadly, just one of those things we have to live with sadly. The denoiser issues should work themselves out if the render is left long enough - but could take hours depending on your GPU. The fireflies are scene specific and depends on your light source, light depth and / or reflective surfaces in the scene (or in this videos example - manufactured fireflies with a Ghost Light) - these sadly won't vanish and will just get worse the longer the render goes .. so drastic measured are needed to swat 'em!

@Porphyrogenitus1 Год назад

Thanks! It's among the reasons I have avoided dark or low-light seens. Unfortunate that it takes the light out of the eyes, tho, since that's a bigger deal to making an image pop than people (including I for a long time) consciously realize.

@RaukoDaz3D Год назад

The highlight can easily be put back in .. just use the Spot Render tool on the eyes as a separate render (with Noise Degrain set to 0) and combine the two in a paint package .. the only problem with this workaround is if the fireflies themselves are showing on the eyes!

@Porphyrogenitus1 Год назад

Solved my problem with Quinfin hair! My lighting is immaculate, so I couldn't believe how I was getting these again after I fixed it for my other characters with relighting the scenes and optimizing my tone mapping settings. This fixed the issue with the hair. I don't know why that hair caused that, but I'm sure glad it's been neutralized!

@IngemarGustavsson Год назад

Great Turorial (as usual) but I do miss what the other two controllers underneath would add to the result: Noise Degrain Radius and Noise Degrain Blur Difference. I have a feeling that tweaking them a bit would improve the result a bit further. Something like you do in Photoshop with the Unsharp Mask and Gaussian Blur settings. P.S. Thanks for adding that thing about Ghost Lights can produce fireflies too. For a long while I couldn't grasp what was wrong D.S.

@RaukoDaz3D Год назад

Confession time .. I've never actually played around with those sliders .. I'll have to have a look into them and see what they do and when they can be used .. if there's anything interesting to report - I'll do a video on them!

@mikael2670 Год назад

Another way i found was actually to tell iray what the nominal light strength is supposed to be at. Nominal Luminance around 200-250 seems to do the trick most of the time as a ray sent through limbo will still have some data to work with rather than cause a firefly to appear. Used to struggle with fireflies especially in dark or very high contrast environments with semi reflective materials.

@RaukoDaz3D Год назад

Yeah, Nominal Luminance should do the trick - but, truth is, I've never really messed around with it and usually just went with the method in this video.

@SmokeyLaBear Год назад

Hey Rauko, Would you consider making a review of Genesis 9? By that I mean an in-depth discussion of the pros and cons of G9 compared to G8. Although G9 released a few months ago, there's a lack of detailed G9 reviews out there. Thanks, and keep up the good work.

@RaukoDaz3D Год назад

Hey Smokey - to be honest, I don't really have much to say about G9 at the moment as I've not played around that much with it .. I think the Daz Originals that have been released (Vicki .. Michael etc) are really good .. but the rest that have been released - I see no difference in quality over G8 .. a couple of differences here and there but nothing much to justify a new Genesis ... It's more Genesis 8.2 to me ..

@edlondon3717 Год назад

Nice tip Rauko! I would think using the filter would be a time saver compared to having to remove hundreds of fireflies in post. Replacing a couple of eye highlights and maybe a few elsewhere is so much easier in my opinion. I am wondering is it possible to increase the filter less than 1...say .5 or .75 if that would make any difference?

@RaukoDaz3D Год назад

It's always going to be image dependent .. sometimes it might just better to sort out in post if there's not much in the way of fireflies .. the little loss in sharpness in some areas could be a tall price to pay for some .. but like I say .. all image dependent. As for .5 and .75 .. sadly, it looks like the slider only works with integers!

@snaketto1 Год назад

thank you for this i have issue with g9 i made custom hands morph and lag add some details but after i import these two the model/mesh get distorted this problem only happens for g9 i use same settings for g8 and it work

@RaukoDaz3D Год назад

As I don't know exactly what you've done with the custom morph it's hard for me to comment - but you should be aware the G9 has a) extra bones on the hands that aren't present in G8 and b) the bones themselves are named differently in G9 .... so if you're using the "same settings" for G8 and G9 characters - then that might be something to look into.

@exodu5123 Год назад

tx for the video sir. also if someone could help me with this problem ive been having . in my renders there are black ring around my char's iris. now ive done some research about the char being far from the origin and u can fix it with memory option in optimisation. but my char is still rendering the rings even when with tha fix.thanks

@RaukoDaz3D Год назад

Hey there - the Memory / Speed optimisation should sort the issue out (if one isn't working - try the other) .. but if not then the only other possible cause of the issue is the model in question being positioned away from the XYZ position of 0,0,0 .. this eye problem (along with the similar hair artefact problem) can get worse the more the model is positioned away from that 0,0,0 coordinate .. give it a try although it means reposition all your elements in your scene so that everything fits.

@exodu5123 Год назад

@@RaukoDaz3D thank u for the reply sir, i will be repositioning everything close to 0,0,0.

@mikeschmidt4624 Год назад

I never see it mentioned that denoising isn't all or nothing. Denoising the entire image usually results in loss of detail and sharpness, even if the original image isn't that noisy to begin with. What I do is run the image through an external denoiser. imo the Intel or Nvidia ones look the best, they're free and based off machine-learning. You could also use the post-denoiser that comes with Daz so you don't have to re-render again. It doesn't look as great, but it shouldn't matter if you use this method. I overlap the original image over the denoised image in a photo editing software and erase parts of the original image so the denoised image comes through. It should be almost imperceptible if you stick to the background and the shadows, the places where the fireflies will be the worst. That way you can maintain detail in the skin, clothes, etc, which will probably be the best lit parts. EDIT: But the tips in the video are great! probably as good as it gets without post-work.

@RaukoDaz3D Год назад

Hey Mike - it's a good tip with denoising in general to do as you say. I used to do something similar myself with the denoiser but not with an external denoiser. I'd render out to X number of iterations. Stop the render .. go to the folder that stores the temporary render when it's finished and load that into photoshop .. then render 1 more frame after turning the denoiser on .. so I'm left with 2 images .. one of them denoised, one of them not .. and then just blend them together in photoshop as I see fit ..

@tak5iio 2 месяца назад

i notice some of my renders has grain and fireflies, not all tho. but only noticeable when i zoom in really close, not from not zooming. should i leave it alone? btw most of my shots are taken from far away that have grain and fireflies. upclose i don't run into any issues with it

@RaukoDaz3D 2 месяца назад

The grain will just come from the render not being fully complete. Leave the render long enough (or use the in-built denoiser : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4opzWycb0i8.html) and that grain will eventually clear up. Fireflies never disappear - in fact, sometimes they can get worse the longer the image renders and they'll always be single color dots (usually white) .. get rid of those by following the steps in this video.

@JohnnyM4all Год назад

It happened with me once because I was using a 3delight environment material in an Iray render.

@RaukoDaz3D Год назад

:) .. that won't help .. but yeah, there are a number of different ways we can get infested with fireflies ..

@dragongaiden1992 8 месяцев назад

Hello friend, I followed your steps and it didn't work for me. I don't know if it's because the scene is very dark or maybe because sometimes when lights cross, these white dots start to appear. I would like to know if you can talk about how to make a clean render without noise without white points, if a filter has to be activated, If you can give a configuration so that one can make a good defined render, I would appreciate it.

@RaukoDaz3D 8 месяцев назад

Hey there - you'll see that there are multiple settings for the "Noise Degrain Filtering" slider .. try it at higher levels to see if that makes any difference. It should remove the white dots at some setting. However, if you're still getting them then check you're scene for reflective surfaces as these can sometimes cause the fireflies in some circumstances .. if you find one - remove it from the scene and do a test render .. keep repeating with anything reflective (even a small piece of metal on a button can cause them at times .. when you find the offending object .. then either remove it from the scene if you can do without it - or adjust the Glossy settings in the surfaces tab for that texture.

@dragongaiden1992 8 месяцев назад

Thank you very much for your comment friend.

@MrFotow Год назад

It definetely helps but it looks to me that your image becomes quite a bit softer (as I would expect from a noise reduction). Just by eyeballing it I would say you lost around 3 to 5% contrast which is very noticable in the hair and in the fine detail of the outfit on the breasts. I wish Daz would introduce masking so you could choose where and where not to apply a filter.

@RaukoDaz3D Год назад

Yeah, I agree - any type of filter - whether this or the denoiser will lose a little bit of sharpness (until the algorithms get much better) .. it becomes a choice on the users part whether or not to sort the fireflies out in post - which could take a while or a short amount of time depending on the scene or putting up with a little loss in sharpness. Of course, it will always be image dependent .. an image with lots of little highlights could get a little dulled in areas while other images might not see much .. if any .. reduction. It's all give and take!

@georgebailey8179 Год назад

You could always use masks in a picture editor and stitch the two together, though I agree that it would be better if Daz gave that in the app.

Hey there - go to Render Settings tab, then to Progressive Rendering. Max Time shows how many seconds (7200 is 2 hours) - Change it to what you want. Hope that helps! (From Google Translate) : Hola, ve a la pestaña Configuración de renderizado y luego a Renderizado progresivo. Max Time muestra cuántos segundos (7200 son 2 horas). Cámbielo a lo que desee.

Thanks again for the video and I'll give it a go next time I might need it! However, for quite some time I've been setting the, Nominal Luminance to 200, as recommended by ITRoy, and it has been doing a fine job in low-lit areas. I know this also has some detrimental effects on some of the Rendering outcome, but I can't say I've seen any problems yet!

@RaukoDaz3D Год назад

I've never really had any joy with nominal luminance .. but then - I've never pushed it up to those kind of numbers so that's maybe why .. perhaps I'll have a look at it again!
