Hi ,
I downloaded the files you provided, thank you for that. I created a new code project using the first person template and replaced all of the existing code with the files you provided. After recreating the original code you were using and moving the player start some ways into the air, I played the game in PIE mode and after landing did not see any jitter when moving the camera. I do have some additional questions, though.
- What version of the Engine are you using? I was trying with version 4.7.5 built from source code.
- From the Vine you linked to, it looks like the level itself is moving (or rotating). Is that correct?
- Is my test case of moving the player start into the air and letting the character fall until it lands appropriate for this issue?
- Do you see this jitter happen in PIE mode, or are you using Standalone or a packaged game?
