# Can I customize the materials and shaders? It is possible to replace the material used for either the terrain or the clipping volume wall. When doing this, it is recommended to make a copy of the base shaders, which are imported as part of the NuGet package under *lib\unity\map\Resources*. Use the copies made of these shaders as the starting point for new materials. Importantly, the `ENABLE_ELEVATION_TEXTURE` keyword used by the shaders will need to be maintained. Certain draw calls for the terrain require an elevation texture while others do not. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
