This guy I was watching, was playing HCF. Basically, I looked down to see his gear and it showed that his sword had no enchantments on it, but when he had the sword in his hand it was enchanted. So, I know this is an odd request, but does anyone know how to do that? It just looks really cool to me and I was wondering if anyone knew. I looked around all over the internet everywhere and I couldn't find anything. Sorry if it's weird I just really liked the look of it.
Here's the video (To see it go to 4:51) :
I also attached an image for you guys to see
(P.S I don't know if it's a mod or if it's a texturepack"
