Any help with Red Giant VFX Bang ?

The front view isn't using the same camera as your Active View. These views are meant for positioning and layout, not for final renders, and they don't support things like depth of field or perspective.. If you want your front view to match, then you need to switch it to the Active View so you have two instances of the same view.

Here's some info from the AE documentation: https://helpx.adobe.com/after-effects/using/modifying-using-views.html

The working 3D views include the custom and fixed orthographic views (Front, Left, Top, Back, Right, or Bottom). The orthographic views show layer positions in the composition but don't show perspective. The working 3D views are not associated with a camera layer. The working 3D views are useful for placing and previewing elements in a 3D scene. 3D layers appear in working 3D views – 2D layers don't appear in working 3D views.
