Why is the camera so problematic?

You might need to adjust the near clip plane. You can adjust it here

A lower value should do it. You might have to restart the project.

You might also get some mileage by tuning the collision profile of the attached asset.

While setting the arm length to 200 and looking upward, it remove the attached asset as shown in the video.
Camera is attached to spring arm. While changing the length to 250 it doesn’t remove the asset.

clip plane is already 1 and yesterday Everything was working fine.
Today I started the engine and saw this issue.

Tested in the new project with the same settings and the same same mesh works perfectly… I have no Idea what happened to old project.

Strange…
