Since demos, spectating, camera tool, and other terms are all different but are mainly "close enough", I will refer to these items as "Camera Tool". In short TF2CT; Titanfall 2 Camera Tool.
Titanfall 2 Camera Tool's are broken fundamentally. There is a chance for this to be fixed, but we'd need help from Northstar devs. As they are very skilled and conquered thought to be impossible tasks such as custom models, custom animations, custom maps, and custom textures.
