Hello!
I have problem with shaking camera.
I made simple fps movement using Rigidbody and AddForce method.
Everything is fine but, when I am adding to some object on scene a rigidbody component camera doesn’t work smoothly. Everything starts shaking a little .
You roughly described a symptom but please read what you wrote; you didn’t ask a question nor provide any details that could be used to provide any help. Nobody can see your project, its construction, what scripts you’ve got, what they’re doing and when things are happening nor see the symptom you mentioned.
If you want help, you have to put in some effort, fully describing what the problem is, what you’re doing and what you’ve tried to resolve it (debugging).
Even with that it might not be possible to figure out what you’re doing wrong but with your low effort post, it’s unfortunately impossible to help.
