Extended Support Structures allow you to link togehter Blast Objects. For example you could link together walls and a ceiling and if the walls were destroyed the ceiling would fall

Extended Support Structure Settings
-------------------------------------

* **Extended Support Icon** - The extended support icon looks like a simple wireframe house when added to your level.

* **Structure Actors** - The *Stucture Actor* array allws you to add *Blast Assets* or Blast BluePrints to the *Exteneded Support Structure*. 

* **All other Parameters** are the same as any *Blast Asset*. **Link:** :ref:`BlastUe4_BlastSettings`

Using Extended Support Structures
-------------------------------------------
1) Create a set of blast assets you want to assemble into a Structure. We'll be using BM_Wall_Door for this example.

2) Assemble the assets in level. Make sure the assets are touching.

3) If you want to have the structure fixed in place add a *Blast Glue Asset*. If you're using *Blast Glue* make sure you enable the *Supported by World* toggle in the Extended Support Structure Properties.
