Using trails in local space/viewmodel space

[dogeascrap (kuda)]

Im trying to use trails to add an effect behind a knife i made in Roblox studio, this knife is inside of a viewmodel. I’m wanting the trail to follow behind the knife but NOT be affected by camera/player movement, i only want the animation of the knife to affect the trail. does anyone know of any methods i can use for this. An example of what I want is like the karambit in Hypershot, somehow they have a trail that isn’t affected by the camera/player movement.
If anyone knows how to help me please do.
