# Multi Shader
The Multi Shader is a custom Shader you can assign your materials to to function for [Terraformer](https://docs.moonlander.ai/explore-topics/generator/global-generator/terraformergenerator) and conforming objects to the terrain in [objectplacementgenerator](https://docs.moonlander.ai/explore-topics/generator/bounds-generator/objectplacementgenerator "mention"). With Multi Shader you can quickly apply terrain customisation to your materials.
{% hint style="warning" %}
Warning! The Multi Shader will overwrite the files of the Materials that you convert, so be careful of which Materials you use. When testing, make sure you have a backup of your materials before converting.
{% endhint %}
You can convert your own materials as follows:
Step 1: In the menu, go to MoonlanderSDK > Terraformer > Multi Shader Converter.
Step 2: Move a material file (.mat) to the Multi Shader Converter and press 'Convert Materials'.
This will convert your material to a Multi Shader. You can now modify your assets with [terraformergenerator](https://docs.moonlander.ai/explore-topics/generator/global-generator/terraformergenerator "mention") and [objectplacementgenerator](https://docs.moonlander.ai/explore-topics/generator/bounds-generator/objectplacementgenerator "mention").
Step 3: Test if your new materials have been converted!
Move your asset to the scene and hover zoom in on the asset. Now add some Snow in the Top Weather Cover of the [terraformergenerator](https://docs.moonlander.ai/explore-topics/generator/global-generator/terraformergenerator "mention"). If everything works correctly, you should be able to see snow on your scene.
