All language subtitles for 25-CrackAO

Now, if we take a look at the cracks,
they look pretty good in Cycles,

as they get a lot of contrast from the
strong path traced shadow. But in Eevee,

they don't really stand out, due to the
lack of real displacement. So to make it

look better in both render engines, we can fake
some ambient occlusion, to boost the contrast.

So let's make some space, here at the color setup.

Then let's duplicate one of these Map Range nodes,
so that we can compute the amount of darkening

we want. Let's connect the masked cracks, as we
only want to darken the cracks within the bricks.

And then let's copy the background
color to this node as well.

Let's get another multiply in here,
for our new texture, and plug it in.

Now let's reset the input range, and then
we see that the bricks get much darker.

This is the opposite of what we want,
as we want to keep the brick color,

and only darken the cracks. So
let's invert the output range.

This makes the cracks stand out a lot more,

and even if we zoom out, they are still clearly
visible, and don't just fade into the bricks.

Then let's name this Cracks, and copy it to
the corresponding multiplication, with Shift+V.

While we're at it, let's also name this other node
that we used for the general ambient occlusion.
