Hey Ruan here from TunnelvizionTV and in this tutorial I'm going to show you guys how to
create clean renders in Modo.
Now before we start I just want to say I'm not a Modo rendering expert so these are just
a few tweaks that I found and that's working for me to remove some of the noise in your
Modo renders.
So let's just quickly go over the scene - I have a teapot as you can see, and I've got
a floor and obviously a camera and then I created an area light - just one area light
off to the side.
And if we quickly look at my materials - so I created a material for the teapot and that's
set to 50% specular and 5% roughness and then the same thing for the floor material.
I set that to 50% specular and 5% roughness.
Everything is close to default settings I actually lowered some of the render settings
but I will show you that as we go along just so that you can see the difference on YouTube
obviously YouTube will compress the footage and hopefully you will see the difference
but let's do a quick render with the default settings and let's see what we have.
Ok so that's the render with the default Modo settings and as you can se we've got some
very ugly noise in the reflection here on the floor, some noise on the reflection areas
on the teapot itself and if you look at the shadows - it's also very noise - I'm just
going to zoom in here a bit say 400% so let's look at the reflection on the teapot, very
noisy around the edges and you get these bright little dots, same with the reflection on the
floor actually a bit worse, alot of these speckles around it and then if we go over
to the shadow we can see the shadow is also pretty noisy.
So let's just zoom out here quickly and let's look at the shadow area first - let's see
how easy it is to resolve the noise or to remove some of the noise in the shadows.
So I'm just going to close this and really simple - going to go to my render settings
and then I'm going to go to the settings tab on the side and then go down to your light
samples.
Now I think this is usually on 64 when you open Modo I just lowered it to 16 so that
you can see the difference, so I'm going to set this to let's set this to 512 - now you
can set this to higher values, you can set it to 256 if you want to save a bit of rendering
time or if you don't mind that your render will take a bit longer you can set this to
2000 or 4000 but I'm going to set mine to 512 and then press render again and let's
see what we have.
Right so our render is finished let's quickly compare it to our first render - so that was
the first render and this is our new render.
Now if we zoom in here, let's go to 400% again and let's look at our shadow - so that's our
new shadow with the new render and this is our first render and hopefully you can see
it's a huge difference just by changing that one setting.
So that's looking pretty good so let's close that quickly and yeah so that's the setting
the light samples under your render settings and then settings here on the side.
Very quickly how to get that noise out of your shadows.
Now let's see if we can do something about these reflections on the floor.
So I'm going to go into the floor material and then you will see something that's called
reflection rays.
Currently this is set to 16 I think the default is also set to 64 but for this tutorial purposes
I lowered it to 16 and now I am going to increase this one as well to 512.
That's only for the floor only on the floor material let's hit render and see what we
get.
Ok so let's look at the difference if we look at the first render we can see a lot of noise
here in the reflections on the floor and if we look at the latest render we can see it's
much cleaner so let's quickly go to 400% and just zoom in here a bit so that's our new
render and that's our first render, big difference.
So let's just zoom out again and lastly let's try to fix the noise on the actual teapot
so I'm going to close that down and then I'm going to go to my teapot material settings
and I'm going to change the reflection rays to 512 and then render again.
Ok so this render is done and as you can see we have some nice clean reflections on the
teapot itself and clean reflections on the floor and nice clean shadows as well so let's
quickly compare that to our first render you can see we have all this noise here in the
reflection area and also very noisy shadows and if we look at our latest one, bit difference
- now obviously this will increase your render time but usually if you want to get rid of
some noise you need to sacrifice time.
