The Scene View Panel is an UI Element on top of your scene view that offers a shortcut to the Gaia Manager, but also helps you navigate in your Gaia scene, especially if you are using Terrain Loading in Gaia Pro.

Configuring the Size and Position

Per Default the Scene View Panel appears centered on top of your scene view. If this is inconvenient for you, or you do not want to use the scene view panel at all, you can re-position it in the Gaia Settings. Locate the Gaia Settings file under

Assets\Procedural Worlds\Gaia\Settings

and adjust the following Settings to configure the scene view panel appearance to your liking:

You can adjust both the position and the size of the panel in the scene view. Note that you can change between "Absolute" and "Relative" types, when making an absolute entry the values that you enter will be counted as pixels (e.g. 50 pixels from the left side of the scene view), when making a relative entry it is counted as a percentage of the scene view size (e.g. at 50% of the current scene view width).

If you do not want the scene view to appear at all, you can give it a large negative value on the y-position to move it out of the scene view completely.

Control your Scene with Terrain Loading

When using Terrain Loading in Gaia Pro, you can access multiple shortcuts to control scene loading and navigating your world. By clicking on the small downwards triangle, you can unfold the panel to access these settings (Gaia Pro only):

In the unfolded panel you can access the following features:

Tile X / ZJump directly to a terrain at the corresponding X-Z coordinate. If your loading is centered on the scene view camera (see "Loading Range" below) and you are close enough to the terrain, it will load in automatically.
Origin ShiftAllows you to shift the entire scene (!) to counter issues with floating point precision.
For example if you enter "500" for the X value, the entire world will be shifted by 500 units so that the coordinate you entered becomes the new X=0 Y=0 Z=0.
If you encounter issues with floating point precision you can use this to temporarily shift your world while editing. 
Loading RangeThe loading range for loading terrains in the scene view. While you can configure the Gaia tools such as the stamper or the spawner to load terrains automatically, it can be more convenient to have terrains loaded in the scene view permanently while working on them. With the dropdown to the right you can control whether this loading range should be applied to the World Origin (X=0 Y=0 Z=0 ) or from the scene view camera position.
If the latter is chosen, the terrains will load in and out following your scene view camera.
Impostor Loading Range / "Create Impostor Terrains..." ButtonGaia allows you to create so-called Impostor terrains that are simple mesh representations of your full unity terrains. These Impostors can then be displayed in place of the "full" terrains to save performance and allow for a higher viewing distance.

If you have not yet created Impostor Terrains, you will see a button to open the Terrain Mesh Exporter to create those impostors.

As soon as Impostor terrains are created for your scene, this button will turn into an input field for Impostor Loading Range. This allows you to enter another range at which the impostor terrains will be loaded in the scene. This works in connection with the Loading Range setting above. Note that if both the full and the impostor terrain are within their respective ranges, Gaia will display the full terrain. So normally you would want the Impostor Loading Range to be larger than the regular Loading Range, so that the full terrains are displayed close to the loading position, while the impostors are loaded in at a higher distance.
"Show Loader Manager..." ButtonOpens the Terrain Loader Manager which allows you to access more advanced terrain loading settings and gives an overview over all available terrain scenes and the existing loader types who access those terrains.
Show Loading RangesShows the Regular and Impostor Loading Range as Gizmo in the scene view. Works only when the scene view loading is centered on the World Origin.
Show Terrain BoundsDisplays a Box for each loadable Terrain in your scene. This allows you to estimate positions and dimensions of your scene even if only a few terrains are loaded in.

Switching between World Map and Terrains when using the World Designer

When exporting your terrain from the World Designer, the Scene View Panel will get two additional buttons:

These allow you to switch between your actual terrains which you exported from the World Designer and the high-level world map where you designed the shape and the stamp distribution.
