For my friends model of the locomotive featured in the film i scripted this so he could “melt” the rails just like casey if he goes above a certain speed (no the cursed engine is not my friends engine it is an old freemodel i had to make work)
this is the original scene in the film
really like heated rails effect… did you just tween the color between white and yellow?
the real question is does the track melt 
?
Other than that this script looks great to me!
the track doesnt actually melt as the engine is just for inserting into games with f3x or whatever and i didnt use tween i used lerp or something like that
