Hey,
Thanks for helping me out.
So, in order, when I was having the problem with the camera, I tried also to lock the camera cuts with the right camera, but was giving me the same result.
Point it, that point of view doesn’t exists in the project.
When I suddenly reopened the file, the camera worked…who knows why.
For the exposure, make sense that can’t be 100% what I see in the viewport…but…
I’m using already exposure on manual( screenshot attached), but the results it’s not correct.
also 
, because you mentioned the exposure in manual…I had also another problem,aha.
if I tried to animate the exposure…I think there is a big bug
I’m a super rookie with unreal…but it got my nerves already
