**(combobox):** Parent material to which the input material is added.
**Add Mesh:** The new mesh that is added to the parent mesh. Clipping geometry is **NOT** automatically removed, there are [[/w/mutable/unreal-engine-4/user-documentation/remove-unseen-parts/|specific procedures to achieve that]].
**(parent material image name):** Image added to the the parent material. There is one input image for each corresponging image of the parent material.
The parent material mesh layout partition size defines the relative sizes of the materials. Each of the parent material images resolution defines what is the resolution of one block for that image for the added material. An extend material with a mesh layout with more partitions will use more space at the end, resulting in more detail but also a larger final texture. [[/w/mutable/unreal-engine-4/user-documentation/basic-concepts/#texture-layout-concept|Further details and examples.]]
**Material:** Extended material.
