- [Zach] In this video, let's have a look

on how to use the cubic worlds
shader to color our objects.

So here I opened up the
basic scene preset file

and I selected the props
collection over here

and let's just drag

and drop the cube bottom
from our asset library

into the scene here. Press
alt G to recenter this.

I have the rendered
viewport shading enabled.

And as you can see

we have this light gradient
here on this cube already

because all the objects
here in my asset library

are using the cubic worlds shader already

the cubic worlds shader.

If I quickly go over

to the shading workspace is
nothing else than a node group

which I set up over here.

That means let's press
control space to full screen

the shader editor over here.

And if I select this
press tab, you can see

we have a look inside this node group.

This are just a bunch of
nodes connected to each other.

And if you know a bit about nodes already

this setup is not even complicated.

By the way, in this chapter here

you will also find an optional
bonus video where I go

over on how I set this up in detail.

However, this should not
be part of this video here.

I just want to show you a
how to use this shader here

with all these settings over here

which is basically all you
need to color everything

in the cubic world scene.

I wanted to make the shading process

coloring everything as simple

as creating the cubic worlds assets.

So we don't need any textures.

We don't need anything else.

We just need this one shader here,

which we can use again, and again.

let's quickly remove this material here.

Let's create a new one.

Let's delete the principled shader.

And if you want to add this
shader here to any material

simply press shift A go to
group and click on CW shader

and then connect for example,
that diffuse to the surface

or you can also do it over here

in the properties editor in
the material tab under surface

simply go to group here and
click on CW, shader diffuse.

So that means we don't have to stay

in the shading workspace over
here to change the shader.

We can also do it over here,
which we also have access

to in the creating workspace over here.

So whenever we create an asset

we can do some quick changes over here.

So on this very special default cube

let's have a look on what
these settings are doing.

Maybe let's go over to the
material preview workspace.

Then we can see the effects
on the object a bit better.

First of all, we have the base color where

we can change the color of the object.

Then we have the random color
here, but this only works

if we increase the random value here

I would recommend two increases to one.

Then we can set up a different color here,

like a green tone

and then each time you
duplicate this object

or each time you're
using the same material

on different objects,

each of these objects
will have a different mix

value of these two colors.

You can see each of them
looks a bit different

which is great to quickly
randomize the color of objects.

That means if you're creating, for example

a forest full of trees

you can alter the trunk color
of each tree a little bit.

Although all of them are
using the exact same material.

Let's set the random
value to zero, once again.

let's set the random color back to white

then under specular color,

And this, I usually only use
for transparent materials, but

if you increase this, we have this

very simple specular effect.

And since in the cubic world scenes

we are using the
orthographic view in the end

it will look something like this.

So let's set the color back to black.

Then we can't see the specular anymore.

Then we have the edge gradient for this.

Let's set the bottom gradient

to zero to better see
what's going on here.

And with this we can add
this edge darkening effect,

which I kind of like

because this adds this extra style

or this used effect to these objects.

So they don't look too boring

by just having one plain color.

So, and of course you can control

how strong this effect should be.

And I would play around with this

depending on what objects we
are adding this material on.

For example, if this is a used old object

then we can make this
effect a bit stronger.

If this is something new and fresh

then we can lower this effect.

Then lets set this to zero.

Then we also have this bottom gradient

which adds a gradient
from the bottom to the top

which I think also is a very nice effect

and supports this cubic world style.

And we can then of course, combine those

to have this kind of style

and all these effects are
generated procedurally.

So it will work on any object.

This is how you use this shader
for any diffuse material.

And now let's see how
we can use transparent

and emission in order to use these effects

I would recommend to switch
over to the shading workspace.

And then all we need to do is to

either connect emission or
transparent over to the surface.

Let's start with emission and here

everything works the same as before.

The only difference here is

that we need to increase the
emission of value down here.

And then we have a kind

of glowing material, which we, by the way

can better see if we are
enabling the bloom effect.

If I increase the emission

you can really see how
this starts to glow.

Okay. Let's not overdo it, but this

we usually use for any kind

of energy effects or for
fire and stuff like this.

So basic color, random gradient

and so on works the same over here.

Then let's connect this
to transparent by default

we can't see anything
because on the one hand

we have to increase the transparent value.

Maybe let's reset the base color to white

simply hover above this
wheel and press backspace.

And in EEVEE here in order
to make transparency work

the object needs to be selected,
go to material settings.

And down here, let's change the blend mode

to aplha blend and the
shadow mode to aplha hashed.

This allows us to have on
the one hand transparency

and also to show the
transparency in the shadow.

The good thing is,

this you only need to set up
for the Eevee render engine.

If we are switching over
to cycles, for example

this works by default.

So there we don't need to set

up the transparency in the
settings down here, because

as you can see over here, we
don't even have these settings.

However, let's switch back
to Eevee here because Eevee

we will use most of the time.

And now, by the way, let's
reset the emission to zero

we don't need this anymore.

And now you can see the
bigger you make this value

the less transparent the object becomes

and the smaller you make this value,

the more transparent it becomes.

And this effect we will
use for any kind of glass

or also transparent elements
like smoke, for example.

And by the way, if you find
it weird that we can look

inside the object, you can
also go to the settings here

of the material and
enable back face culling.

Then we can see through the object

but we can't see the inside
of the object, but yeah

this is of course optional.

And we can also change the
color of their transparency.

And in this case, the
specular value makes sense.

So let's increase this to one

let's have a look from the
orthographic perspective.

And this is then how a
glass material for example

would look like. Let's
set this back to black.

And this is how this
cubic worlds shader works

pretty simple to use and all in all,

you can nearly color everything
in this cubic worlds scenes

with this one shader.
