Hi Guys,

please help me. I am rendering a pool scene and the water is very noisy.

The figures and other enviroments looking great at the end of the rendering just the water is noisy. How can I make it smooth without to use denoiser? Thanks.

I think that its highly unlikely that there is something wrong with the rendering settings or with the water shader. Water is costly. I would use spot rendering with denoizer. Trying to limit to only the water and then merge it in photoshop with the main scene. You will need to blend the edges with a mask or you will get a visible seam. I also do this for character faces so I can render it for way more samples without it taking a million years.

Could you expand on that? That sounds really cool!

Eh i don't know what more i could add.
Some things are noisers than others, some things are more important to the image than others, some things react well to the daz denoizer and others result in visual artifacts. it depends. I do consistently run the faces at a higher sample than the rest of the photo.

the original. the noise is especially bad in the face, the body is acceptable and the background is "clear"

i use spot rendering tool on just the face and its super fast. if you dont blur the edges you might end up with some ugly visual artifacts or straight edges that wont clear up when you denoise the image and do other post processing.

You can see where the original meets the more detailed render but its fine. there wont be much detail in that area and it will clear up in post. you apply this to a new layer so that you keep the original renders in case you need them.

How it looks at the end. You cant see where they meet and this is very zoomed in.

Hope I did it well this time!?

Perfect !

(Tbh, on the couch one, I didn't even think how accurate or not it was. Now I know I always should.)

If you have the right assets, accuracy is always appreciated.

I think your problem is with the lighting. Depending on the position of your lighting (spotlight, etc.), this can cause grain in the water.

here's a small example, this image was rendered with 500 iterations, one with a spotlight directed towards the water and the other with a hdri source only.

with spotlight


with hdri only

Thanks for taking the time explaining this.

Thanks for taking the time explaining this.

Depending on how many light sources you have and how bright they are they add a lot of noise to the image which is percieved as grain. You will either need to tweak light settings or you need more iterations.

Thank you. I will try it for sure and I guess you have right with the lighting.

Which one?

Which one?

Both in fact ! The grain of the first is ! The light of the second is ! the results are great

Does that means she's not coming on then?

Try this one already denoised as .jpg It may do what you want... and may not could try I guess
