Hello and welcome back everyone to Stylish Environment with Blender 4 in Geometry Node.

In the last lesson we left ourselves off with a nice setup for Ambient Occlusion that highlights

the overall composition and refines some of those shapes out of this setup.

Now we're going to go ahead and get even more detail, extra detail, especially making use

out of the lantern setup over here to get a bit of a glaring effect to make sure that

it looks like it's actually being lit up in regards to this entire setup for the lantern.

So for us to do that we're going to make use out of something called, let me have a look,

Emission.

So this is the color information that we're looking for.

We're just going to basically make use out of it to give us a glaring effect.

For us to do that, I'm going to actually just move this out of the way a little bit so it wouldn't be as confusing.

Subtitled by online-courses.club We compress knowledge for you!

For us to do that, we're going to just drag this on from Emission, like so, and we're going to search for something called Glare.

So Glare, if we just keep it as default, we can click CTRL-SHIFT and tap over here, we can see that this is the effect we're getting.

So already it's looking quite nice, but this is not the type of a setup that we're looking for.

What we're looking for is something called, if we look at the options that we have, something called Fog Glow.

Fog Glow will allow us to give us that soft lighting and nice setup, like so.

So already it's going to give us just a good look for the glare effect.

If we were to increase the mix, we can see what it gives us. Basically the mix just makes up the original one.

And the effect, so...

the extreme values are quite a bit too much. If we were to keep this at 0.1, the default value,

it should be looking quite nice. The threshold is going to be, basically,

affecting how much of brightness affects the glare. So, for example, how much emissiveness

is affecting it. If something is more emissive, we can, for example, target that particular part to

make use out of the glare effect. And if something is not emissive enough,

the threshold will simply ignore it. So, for this reason, we're going to set it up to 0,

because we want both of these glows, both the fountain a little bit, the water, that is,

and the lantern to be glowing slightly with their emissions. We can also increase the size,

which will basically show us how much it is overall affecting it, which is quite nice.

And what's nice about this is that we can actually just simply...

Scroll down a little bit. We can make a duplicate out of this glare and that would simply amplify

the overall result. So for us to click shift and d and make a duplicate and just simply

put it back onto this setup, we can get just a much much better effect. Although we can do that

same thing with the size, sometimes I prefer to just multiply it over like so and that just

amplifies the overall effect quite nicely and quite simply works really well. So now that we

have ourselves a nice glare, let's go ahead and actually add it onto our setup and that is

literally we're going to be adding it onto the image by using a again something called mix color

like so. Then from the already set up ambient occlusion we're going to add in onto the image

like so and then selecting from instead of mix adding the color. So this will basically add the

values.

Basically everything that's bright is going to brighten up even more

and all of those values are going to be added in the areas where it's black.

So it's just going to add a value of zero, which is

black basically in regards to the RGB values.

So it's not going to affect anything that's black, but those areas over here

is just going to amplify the overall setup.

Let me show you how exactly it looks like actually by just adding this image over here

clicking CTRL and SHIFT and tapping on the node and there we go.

We can see that it's a nice, nice glare.

Maybe it's a little bit too much so we can just lower this down

and we can see how it looks like with a smaller amount.

I can even set this to zero and that's going to give us a none.

But if I increase it, I can get a nice bit of a glare.

Set this value to a 0.7 value.

It's going to give us a nice soft type of a glow, which I'm quite keen on.

And I quite like it.

And now we can actually start thinking about the background itself.

If you notice, well, if we look at the image, we have a completely black background.

The reason being is that we've not had anything added to the background itself.

And I think, yeah, the viewer itself is using alpha by default.

If we were to untick this alpha, use alpha, it should give us a different result.

But it's not giving us a different result.

So I'm not sure why. Either way, we need to go ahead and fix that.

We need to change what's inside of this background.

So let's go ahead and go on to our resource pack.

This time we're going to actually go on to the folder itself.

Something called compositor background.

And there is a very nice image.

What I'm going to do is just I'm going to locate it within this folder over here.

And I can simply...

Actually the easiest way would be for me to just...

If I have a folder open I can click and hold and then drag it onto the compositor

and that's going to just bring the node with that image inside.

And just like that we're going to get ourselves this background image.

And all we need to do now is set ourselves up with it.

If we were to click CTRL-SHIFT and just tap on the screen that's how it's going to look like.

And we can also now go ahead and simply

add it within our setup using something called...

If I were to search for something called Alpha Over

Alpha Over will allow us to just simply add this onto our image.

So the default image that we had was over here.

And this is the final result that we currently have.

Let's go ahead and add this onto the image at the bottom basically.

And the one at the top is actually going to be...

Well let's go ahead and see how it looks like.

by clicking ctrl shift and tapping. This is how it's going to look like by default.

If we were to add the image on top like so, we can composite it and nothing is going to work.

The reason being is that we actually need to turn on a small functionality within the blender itself.

Although it says something like use alpha over here and use alpha over here, it's not actually

using alpha. The reason being is that if we were to go on to our render options, we have something

called, if I have a look at the setup, something called film. Let's go ahead and open it up and

there is a small tick called transparent. If we were to tick on transparency, it's going to give

us the transparency with alpha over, but we need now to re-render this image. Let's go ahead and

click f12 and there we go. We see that the background is already giving us that transparency,

so the black and white type of squares indicating that it is in fact transparent.

So let's go ahead and give it some weight and there we go.

Alright, so now we can close this down. We can see that this has in fact

been updated because we enabled alpha right now. This is

actually working with alpha over. So right away we're

going to get ourselves a nice background. Let's talk about, in regards to the background

itself though, just a little bit adjustment and tweaking. So although the

background itself is looking quite nice, we can add a bit of an extra detail.

We can click Shift and A, we can search for Soften. Sorry, not Soften.

It's going to be called, I believe, Filter. Yep, that's the one.

Filter, Soften and it's going to give us this type of a setup.

Soften itself, what it does is basically

it just gives us a, well, blurred out effect.

So before and after.

And actually I will go ahead and go on to the noise real quick and change

this to, maybe just go ahead and have a look.

to none. The reason being is that this is actually going to give us a much faster compositor

and then at the very end we're going to change this to accurate for denoiser for the ambient

occlusion. But for now though let's go ahead and just talk about the soften over here. So it's

looking, just basically softens out, blurs out a little bit of those values so we get ourselves a

nice gradient basically. And I'm actually just going to duplicate it because it's not enough

for me and I'm going to simply add a bit of that extra over here and there we go. That's looking

quite nice. Additional thing that we can do is something called transform. Transform is a nice

tool to make use out of when we want to offset something. So for example over here if I was to

set this value to something like 11, which is going to start compositing, you can see that

the entire setup is moving upwards basically, like so. And based on that we can control

where the gradient we want is going to be set up.

And I want this to be just slightly, slightly higher, maybe

like so. And we can even scale this up a little bit, so for example if we set this

Subtitled by online-courses.club We compress knowledge for you!

something to 10

it's actually going to, I'm not sure if it's visible, but actually it's going to zoom in

to the image. Or if I set this to 0.1

it's actually going to make the image not visible for us.

So let me show you, there we go, that's the image I'm talking about.

So setting it to 0.5 it's actually going to minimize it, but scaling it upwards

sometimes is useful

when we want to have that zoomed in effect a little bit on the image.

So in this case I'd say we can just

zoom in just a little bit, 1.2 is going to give us a great result.

Just slightly zoom it in like so, and you can see version before

and version after, that's how it's going to look like.

And yeah, we're pretty much done with the background itself.

We got ourselves a nice setup. We still need to do some color corrections

some bit with the, if I were to go back, with the environment

itself as well. But we're going to continue on with this in the next lesson.

Thank you so much for watching and I will be seeing you in a bit.
