my 3D level work flow

1. Keaton Bradley
3D game engine workflow
I have been asked to design a 3D level on unity, I have started this by making an environment to
work in. I created this by using the brush tools buy building up hills and making mountains but when
I was doing this it was all un textured, which means that I had to paint a texture on to all of the
ground.
This is my level up to now I hope to add a fort and castles later on in the future.
To add the textures I had to first go in to the assets and then add the texture in to the paint brush so
I could use it here are the tools I will go in to detail by annotating it.
This tool here is use to create mountains and hills you
do this by holding down the mouse button until you
are happy with the hill/mountain you You can change the type of
mountain you get by changing the
brush to get a different shaped
mountain, as in a pointy mounting
or a smooth mounting the brush
tools are here

As you may be able to see, I have completely changed the way the level looks this is due to me not
being able to think of a good design on the design, you may be able to see the blue spot on the level
this is a village I am working on I plan to have a forest a few farms and a wizard tower in the
mountains somewhere.
To add the water into my level I have had to create a plane then add textures on to that plane to get
the look I got I used 3 different textures to get the water look to set the height of the water you have
to use the X, Y and Z coordinates, I have set them to about 24-25. I set it to this because it seemed to
fit to my level height really well.
To create a
plane you have
to go in create
To edit the waters position I have to
use the X, Y, Z coordinates
As I said before I had to use 3
textures to get the texture of water I
wanted the consist of snowflake and
2 water bumps, but on the water
bumps I have put the tiling to 20,
this gives off a wave effect on the
water.

When you start to make your level at first you will start off with a big white tile this is because it is un
textured, so get the shape of world you like, so add mountains islands and dips where you want the
water to go in, once you have done this you can now start to paint. You paint on the level by using
the terrain tab, in the terrain tab you can change the shape of the land and texture it you can also
place down trees by either painting them on or mass placing them which will cover the level in trees.
This tool will raise terrain until you
let go of the left mouse button.
The tool with the both up and
down arrows will raise the terrain
to a set height this is good for
getting you level to a flat surface
to start from.
The two mountains with the rain drop is a
tool which will smooth out the terrain to
make gradual hills so you can walk up and
down them or you can use it to make a
beach going in to the sea.
Now this is the tool which I have
been explaining the paint brush as
you could have guessed allows to
you pain a texture on to your
plain white surface.
The tool with the trees allows you add
tress in to your level, the reason I have
no trees is because they was bugging
out and kept on disappearing.
The tool with the flowers are pretty
much self-explanatory, you guessed
it you can paint on flowers on your
level.

as you may be able to see I have change the water, this is because this water looks a lot better and
has animations when you’re playing the game, the animation is a wave when you ;look near the land
the water will crawl up the land an go back like a tide.
This is a castle I found on the assets store, to get the assets store all you have to do is open google
and search, unityassetsstore and you will be able to download whatever assets you want to,
although moth of the assets you will like you will most likely have to pay for them this is because the

5. Keaton Bradley
people who make will need money to continue to make more assets and maki ng an asset isn’t very
easy and it is extremely time consuming.
All of these trees in the court yard of the castle have mesh colliders on them this is so you cannot
walk through the trees, I could have used a capsule collider but this only covers the trunk of the tree
whereas the mesh collider will cover the branches and leave also. The only problem with using mesh
colliders are that it will increase the lag you have if your machine is very powerful, so if your specs in
your pc are not too good just use capsule colliders rather than a mesh collider.

6. Keaton Bradley
To add a mesh collider you have to click on the asset you would like to have collisions, and then
whilst you are on it you will get a side menu, what you want to do is add a component in the menu
then click on physics. Once you have clicked on physics you can add your colliders the ones you use
for trees are mesh colliders or a capsule collider these are right next to each other in the drop down
menu. On you have done this your tree will have colliders.

To add a sky like mine you have to add a skybox, for this you will need skybox textures you can get
these from the assets store to add the skybox you have to go in to edit then go on render settings
and play about with different skyboxes until you get one you like.
