Future Lighting stuttering?

I am recreating an old ROBLOX game “RED44_SATYR44”, and it’s going pretty well, however I want to fix the flashlight “light” and potentially the light cookie to make a smooth experience for players.

The light seems to have a stutter or it doesn’t update to the smallest changes of its position/orientation. With an animation on my viewmodel, the light is constantly but subtly moving so this problem greatly affects my attention, and will definitely stand out. I’m trying to figure out whether or not it’s either a future lighting bug, or the way my viewmodel is set up.

The way my viewmodel handles displaying the light, is having a part attached to the hand bone using a RigidConstraint. The flashlight cookie is then welded to that part.

I have looked on the devforum for an answer, or even a problem similar to mine. But given that there is no real close problem that I’ve found (I’d appreciate a link if there is), I’m assuming it’s just a RigidConstraint flaw, and that I’ll have to do in Blender and just implement the parts there as part of the rig to begin with.

Any help would be appreciated!

I dunno much about constraints but what if you used a different one that isn’t ridged constraint? One that allows for more wiggle room but not too much. You might need to edit the parameters.
