PointLight No Longer always Follows HumanoidRootPart in Future Lighting

Summary:
PointLights attached to a character’s HumanoidRootPart no longer properly follow the player’s position when using Future lighting on low-end or emulated mobile hardware. The light appears to trail behind the character or becomes visually detached from the expected source. It will then sometimes appear to snap to the player’s location.

Steps to Reproduce:

  • Open Roblox Studio with Future lighting enabled.
  • Set time of day to nighttime to reduce visibility.
  • Attach a PointLight to a HumanoidRootPart of a basic character.
  • Set graphics quality to low and emulate a low-end mobile device.
  • Move the character.

Expected behavior

Expected Behavior:
The PointLight should move with the HumanoidRootPart, staying locked to its position.

Actual Behavior:
On low-end devices or when emulating mobile settings, the light appears to lag behind or drift from the character. It is most noticeable when moving quickly. This did not occur before the recent engine update and may be related to changes introduced by Unified Lighting.
