How would I make a part trail?

How could I make a part work as if it was a trail, (follows a part, smooth curves, extends the line). I’m not sure how to make it without z-fighting and lag, so I’m asking other people! Thank you

Just add 2 attachments and the Instance trail. Put in the Trail Attachment0 the First attachment and in the part attachment 1 the second one. You can also customizate things as the trail color etc.
Posdata: The attachments must be separated, else it will generate a trail whitout superfice (Invisible)
