Using the Engine

Camera

Once you click on the top-left Render window. You can move the camera freely using:

1. W - forward
2. A - left
3. S - backwards
4. D - right
5. E - up
6. Q - down

If you hold left mouse button, you can freely rotate the camera.

In the top-right Camera window, you can manually select camera's position as well as its:

1. Depth of Field - "blur effect"
2. Focus Distance - focus of the camera
3. Field of View - camera "zoom"

Camera's position can also be manipulated on the plots in the bottom-left window.

Planets

Click "Add New Object" in the World menu in the bottom-right window to create a new planet.

By clicking on one of the planet's names, you can manipulate its:

1. Position
2. Size
3. Texture
4. Remove the object

In the Texture Menu, you can choose planet's color and press Set Color to apply changes or choose one of the preloaded textures.

You have to select Emit Light checkbox in order to emit light from that object. You can also change light's color and intensity. If you want to apply these changes, you have to select the texture again or Set Color.

Ambient Light

Change Ambient Light in the World window to alter the color that the "unvierse" shines onto the objects.

Plots

In the bottom-left window, you can see your world from all three different sides. You can drag and drop the planets as well as the camera. You can also see the focus distance of the camera. This is especially useful if you have high Depth of Field.
