# Set Collision Channels In the **BP\_Arcware\_Pawn** there are 3 different collision settings to be aware of...\ \ **1)** **Collision Channel for DOF:**\ If you are using the setting '**Camera Depth of Field Method** = **Automatic\_Depth\_of\_Field'** ...

... Then you need to be aware of the Collision Channel that's being used to update the Auto depth of field. In it's default set up, any mesh with the **'Visibility'** collision channel set to **'block'** will react to the Automatic depth of field.

**2) Spring Arm Collision Channel:**\ if you are using the **'Orbit Movement Mode'** then a Spring Arm component is being used to rotate the camera around the focus point. If **'Spring Arm Should Collide With Objects?'** is enabled...

... then the Spring Arm component has in-built logic for handling collisions. With the '**Spring Arm Collision Channel'** setting, we can specify a collision channel that will be used to stop the player camera. (useful when you want to stop the user from orbiting through the floor/walls)

**3) Collision Types For Pivot Change:** \ Setting these collision object types, means that you can move the camera pivot point (teleporting) to meshes that are set to **'block'** those collision object types.

Set Collision types for allowing pivot changing
