Then run the program by clicking on it while Unity is open.
Then click "Import"
Another thing you need to do before working on the world is to open up a previous world. This allows you to set the spawn point and change the description, plus it makes things easier for me or others to export.
Click on it to open it.
Obviously, you don't want levitashia in there. Notice the red circle:
This is the Hirearchy. It displays what is in your scene. (AKA, whats in the world currently.) You want to delete everything except for the Base and World.
It should look like this.
If you can see the skybox (the background) and fog, it would be easier to turn them off for now. Click the following buttons.
The picture displays the background and the lightbulb displays light. Turn them both off.
Part 2: Creation Time..?
Now it's time for you to create a terrain. Click on Terrain-Create Terrain.
This should create a blank sheet in the scene. Notice to the right in the Hirearchy and the inspector.
The Inspector displays the properties of the object you have selected. Notice the tools:
What each does:
Red: Molds the terrain upward. Holding shift will lower the terrain. Orange: This will mold the terrain to a specific height. Holding shift sets the point. Yellow: Smooths the terrain. Use this when it's too bumpy. Green: This one paints the terrain with textures. We'll go into it in a bit. Blue: This manages your trees just like the Green manages your textures. Dark Blue: This manages 2d grass and such, just like Blue and Green. Purple: This manages the terrain settings, but it's best to leave these alone for your first world.
Now would be a good time to test out the terrain. Click on the (red) tool and you will see this pop up:
The yellow is pretty streight forward, and the green will adjust the power, or strength, of your brush. The Red displays all of the amazing brushes you have to choose from. Select a brush and draw on the terrain. You may notice it's very similar to painting a picture.
As you can see, it looks dull because there are no textures loaded. Click on the Paintbrush (yellow) tool.
(Note: Target Strength limits the opacity)
Click on the "Edit Textures" (Green box above)
Then Add Texture
This will pop up:
The Yellow will stretch or squish accordingly, and the Red is where you choose your texture. Click on the Red box to choose. This will pop up:
As you can see, it loads every image available, and not all are textures. I have outlined in Yellow those that are actual textures. You can use these, but I strongly suggest you do not, or else it will look like everyone elses world.
How do you get more textures? GOOGLE IMAGES! Search for textures you want, but make sure you include the word "seamless" in your search, or else the textures will not look smooth at all. If you find a texture that is not smooth, I have written another tutorial on making it seamless:
Once you download one that you like, import just like the textures. To make the textures look better, select one each individually and change their wrap mode from "Repeat" to "Clamp."
To set up the skybox, you need to create a material.
Select the new material and change it's render settings to a skybox.
Now you will see 6 areas for your skybox. Put each piece of the skybox into their designated areas.
If you got a skybox from the site recommended above, you will NOT have a bottom texture, (Not a problem) and the LEFT and RIGHT images need to be switched.
Now that your skybox is done, you need to have it displayed.
And this will pop up:
Make sure the skybox material is the skybox you created (Defaulted to "New Material,") and go ahead and change the Fog Color to what ever you like.
Now we need to adjust lighting. Create a directional light.
Position it between you and the sun, then angle it so it is shinning right at you. This will make the terrain look like the light is coming from the skybox. Unfortunetly, I do not have a sun in my skybox, but it is in the right place due to the shading of the skybox.
To make this take effect, create a lightmap.
This will pop up and click OK.
Once that is done, you are ready to export it.
Part 4: Exporting
If you don't have Unity Pro, create a package.
Upload the package to Drop Box, and send it to me or someone else that has Unity Pro to export.
If you have Unity Pro, or the Pro Trial, export it like this:
Make sure it says "Bundle," then export it. The files will be located here:
Upload EVERYTHING is there to Dropbox in it's own folder.
Once that is done, right click the following item to get your URL!
There you have it. That's how to make a world in Unity.
