# Hotspot Materials

Hotspot Materials are specialized materials that attempt to align themselves to the edges of your mesh. Because these materials can align themselves the can greatly speed of up the creation of assets by no longer needing to manually align the material (most of the time).

All Hotspot Materials should be named with a `_hs` near the end of the materials name. this is one of the best indicators that the material is a hotspot. Also those with a keen eye may be able to spot the outlines in the material. 

Here is an example image of the Hotspot Material `reflectivity_hs_30`

# Using Hotspot Materials

Here is an example structure, just a tower a squares with lighting at every corner of the bottom square.

Right now this uses the material `reflectivity_30`

Now if you select a Hotspot Material ( you can search "_hs" is the asset browser to find some ) and then select every face of a mesh you want to apply to.

Then you can click your "Apply Material By Hotspot" button (or by pressing <key>Alt</key>+<key>H</key> ) and apply the material like so.

Here is the same example structure using `reflectivity_hs_30`

notice how the material has aligned itself to each edge of the mesh automatically. 



## Applying Hotspot Materials by face

There is another way to apply hotspot materials based on the faces of the mesh and not just the edges.

When applying your hotspot material, **instead** of pressing the "Apply Material By Hotspot" button, press <key>Alt</key>+**<key>T</key>** ( there is no GUI button available ) 

That will align the material to each face of the mesh like so:
