Layer Tab

This documentation is for update 2.0+, applied to 5.4+.

A Landscape Layer is actually a Material Function created to work specifically with the Landscape Material Tool.

Layer Reference

1. Load a Landscape Layer's data into the Landscape Material Tool.*

2. Load the Landscape Layer (Material Function) currently selected in the Content Browser into the Landscape Material Tool.

3. Browse to the currently-selected Landscape Layer in the Content Browser.

4. Create a new Landscape Layer using the Landscape Material Tool's default Landscape Layer.

5. Apply all changes to the current Layer.

6. Create a copy of the current Layer.

7. Further Actions Menu (see below).

*When a Layer is selected, the box has two states:

• Save to Update!: This Landscape Layer has been created in a past version of the Landscape Material Tool; saving the Landscape Layer through the Landscape Material Tool will automatically update it.

• Valid Layer: This Landscape Layer has been created in this version of the Landscape Material Tool and no further action is needed.

There is also a hidden third state, Invalid Layer, which means this Material Function is not a valid Landscape Layer. However, there are checks when setting this value that should not allow anything invalid to ever be placed here so it should never be seen.

Further Actions Menu

• ACTIONS

  • Reset To Defaults: Reset the current Layer's parameters to the global layer defaults (does not reset the texture inputs).

  • Copy Parameters From Layer: Copy the parameters from another Layer to this Layer (does not copy the texture inputs).

• EDIT LAYER IN MATERIAL: Shortcut to open a Layer present in the selected Master Material.

Layer Reference Toolip

If you hover the Layer Reference box, you will see a tooltip with useful information.

• Section 1: The name of the Landscape Layer Material Function.

• Section 2: Type of asset.

• Section 3: A list of ALL Materials that currently reference this Landscape Layer Material Function.

• Section 4: If this Landscape Layer is in the Master Material, it will show the Blend Type and Noise Layer applied to the Layer in the Material.
