I have an animation and around 20 cameras which have worked fine for months. Suddenly they just stopped working in the viewport. Any ideas on this please? So so annoying. They will no longer switch for some unknown reason. The scene renders the correct camera but its just not good enough, i need to tweak cameras which have been keyed also all th eway to the end of the project. Tried re-appending all to a new scene but no good. Pretty poor this …
