How To Speed Up Your Render 3X Faster Using V-Ray Denoiser - 雙語字幕
Hello guys, welcome to platform studio.
I hope everyone of you guys are doing bouquet and being healthy It's been a long time.
I have done a video and video rendering today I will try to show you how to speed up your render using vres
V-ray denoiser feature.
I have been experimenting with this feature and I got some really good results.
You can speed up your render two or three times like two times or three times using this feature without losing measure render quality.
Oh, another thing.
I have discovered that 88% of my viewers of this channel's not subscribed to channel.
to my channel only 2%
of you guys are subscribed that's that's really sad so my request is if you find this video useful or helpful please do subscribe
I have never asked this before so now let's get into the video So, I have an interior file with lights and camera.
This video is not about light setup or camera setup, so I am not going to show you that.
I have made so many videos about light and camera, but I will show how to speed up your render.
and what to do in render setup.
So go to rendering and render setup.
So in the common tab we have our usual output size as usual 1920 to 1080p
because it's a YouTube video so I have chosen that and then I have saved I have
out render output saved and then links go to the V-Ray tab and here
will change the image sampler to bucket and then bucket image sampler here
in this tab this is the part this is the most important for here the
noise threshold so if you
don't now the lower the noise threshold is the more time you will need to more time the
render will need and the higher the noise threshold is the render will be noisy but
it will take less time so the default near render threshold is 0.1 and we will
keep this 0.1 for this first render to see that how much time does it take to render this particular file.
Then next let's go to GI and select the primary engine as as always irradiance map and secondary
engine light cache and we will the current percent of irradiance map I will choose medium.
If I choose high it will take forever and light cache will take forever.
so that's it just default settings image sampler bucket and global
illumination primary engine is irradiance map that's the change I have made so
let's see how this render comes this this is
looking a little overexposed but trust me it's not I have tested this file
before so I will just frame it and I will fast forward from this moment I will fast forward a 100 times,
the speed of 100 times, so let's see how much time does this render need.
So, two and a half hours later, here we are, this render took two hours 41 minutes and it's
a quite decent render, there is not much noise, it looks okay, it looks good, a little bit of noise.
but it's okay, it's usable and there's nothing really wrong about it from the noise perspective.
There's a little bit of noise just.
So, you can see it took 2 hours and 41 minutes, it's a very long time, so I will try the denoiser method.
So first let's go back to V-ray and noise threshold.
We'll of course the type will be bucket and noise threshold.
So again if you decrease the noise threshold the land render will come cleaner but it will take a very long time and if you increase
the noise threshold the render will come noisy and it will take less time.
So the default was 0.1 and I'm putting just 0.1.
I'm putting just 0.1.
So the render I think is gonna be noisy but I am gonna go to render elements and select V-ray denoiser.
Here V-ray denoiser is okay.
I have selected as gender element.
Now denoiser engine, there are two, because I have an NVIDIA GPU, I can choose NVIDIA or I can choose the default video, denoiser.
In VRIA,
AI is faster but I will choose the default one because it's more accurate and it's flexible, you can choose mid, default, strong or custom.
So I will choose default for this part.
So, here it is, I have changed the noise threshold to 0.1 from 0.1 to 1 and I have added VD
denoiser as render element.
So let's re-render this scene and let's see how much time it takes.
Previously, it 2 hours and 41 minutes.
So let's see, it's building the right cache, it similar, it looks similar.
I will just adjust the frame to match the previous view here.
So, the pre-pass 1, pre 2 or 3, it will take the same amount of time, but the render
time, it will take less time for the render.
So, again will be fast forwarding 100 times for this render because we don't have
we can we can just it's a YouTube video so we have fast forward so I'm fast
forwarding a hundred times and let's see how much time it takes so it's
rendering the passes pre-passes now it's rendering wow this is fast and and noisy this is
no
you can see visible noises over the left side and there's the magic see all the
noises are gone all the noises are gone
because of the V-ray denoiser the noises are gone and the release render
is usable here you have a layer denoiser layer you can turn it on and off and you
can see if you turn it on the noise is gone and if you turn it off the noise is
there so we can remove noise and reduce our render time by using a V-ray denoiser.
So here I have chosen 0.1 it's kind of it's it's extreme because it's a tutorial video you can play with it you can choose 0.5 0.6 or 0.7
according to your
you have how many projects you have to render you can choose your noise threshold but for
this tutorial to show the process I have chosen 0.1.
so this was our video if you guys
enjoy if you guys liked it please let me know in the comments thank you very much and
please do subscribe love you all guys be healthy be happy bye You
