View source for Using Weightmaps to texture a Landscape

{{Rating|Type=Article|Versions=(please verify)}}
==Overview==
So, here is a little tutorial on how to use weightmaps to texture your landscape. It assumes that you have read and understood the documentation about landscapes.

This tutorial requires you to have a heightmap and the associated weightmaps. If don't have a finished terrain, have a look at TerreSculptor or World Machine to create them. While this document is using a non tiled terrain component, it should be noted that given the current version of Terresculptor is Alpha ( I've had no problems with it myself ) that it currently does not support exporting tiled terrains , which UE4 supports.

For this tutorial I am going to use a 16-Bit RAW format for the heightmap and 8-Bit PNG files for the weightmaps. 

==Importing the Heightmap==
First you need to create a new landscape and choose "Import from file":

Select your heightmap file click import.

==Creating a Landscape Material==

In the next step we have to create a material for the landscape. We need a seperate layer for each weightmap we have. The image below is showing a simple Landscape texture with three layers (snow, rock, grass).

Save the material and apply it to the Landscape. 

==Importing the heightmaps==

Navigate to the Landscape Options, choose Paint and scroll down until you see the "Target Layers" options:

Create a new Layer Info by clicking on the little "plus"-sign. Choose "Weight-Blended Layer". After that right-click on the Layer Info and choose "Import from file":

Choose your heightmap and repeat this step for all your layers.

And that's it. Your layers should now be imported and the terrain should be textured accordingly.
