Netflix Superheated sword effect. [Mod Request]

[Xamer95]

So I just rewatched episode 3 of season 2 of the netflix where geralt thinks hes gonna beat down a leshy, where he superheats his sword with igni, I would love for a mod to be implemented on a version of a sword if possible, ( I am working on a cinematic cut of the Witcher 3 and it would be awesome if someone could make it)

I know you can get it flaming, flames spread across the sword etc, but having it superheated for specific scenes would be amazing, and a cool mod in general. Check image below for reference to get the idea.
