In an update that I must admit comes as a rather pleasant surprise, Beamdog has recently unleashed a nice and chunky graphical overhaul for Neverwinter Nights: Enhanced Edition. After several years of hard work, the freshly released update has now added HD character models & textures to the game, which as you might judge from the two screenshots, really do look quite lovely considering how old the game truly is!
However, while all of the new models are fully customizable and can be further modded by the community, there is a chance the HD Pack might not play well with your current (and likely considerable) list of mods. So if you do decide to grab it, I'd recommend first backing everything up before installation, just to be on the safe side.
Speaking of installation, you'll need to go through Beamdog's website in order to grab the HD Pack. Thankfully, the whole process is fairly simple. All you need to do is download the 4.1 GB HD Pack near the bottom of the website, go through the automated installation process, and you'll be able to enjoy your character's fancy new look in no time.
Have fun accessorizing, and here's to hoping we'll see more of these types of nifty updates for Neverwinter Nights in the future as well.
