The green line in Roblox Camera is usually either a constraint/weld visual in Studio or a GUI alignment guide, not the camera itself. In most cases, you can hide it by turning off the visual aids or exiting the editor mode that’s showing them.

What to try

  1. Press Alt + D in Roblox Studio to hide constraint visuals like weld lines and attachment indicators.
  1. If you are editing a GUI, close the GUI editor or stop dragging the element; the green and red guide lines are alignment helpers and usually disappear when you are not moving UI objects.
  1. Check the model’s welds/constraints and disable their visibility in the properties if the line is attached to a rig or character.
  1. If the problem is a camera or lighting glitch in an actual game, it may be a separate rendering issue rather than a line overlay. Reports of green-screen or green artifact problems in Roblox often point to script, lighting, or graphics conflicts.

Most likely fix

If you mean a line visible in Roblox Studio while building, Alt + D is the first thing to try because it hides the common constraint visuals immediately.

If it still shows up

  • Restart Studio.
  • Check whether a plugin is drawing helper lines.
  • Test in a fresh place or with the character/model removed to see whether the line comes from a specific rig or attachment.

Quick note

If the line appears only while moving UI elements, it is normal and meant to help with alignment. If it appears in the game camera itself, the issue is more likely a rendering or script problem than a camera setting.

TL;DR: Try Alt + D first, then check constraints, welds, and GUI alignment guides.
