Then the translation was inaccurate, which is not the first case in english translations. It's "opaska" in polish which means "band", "bandana" would be "chustka". The Sword Of Destiny, A Shard Of Ice, part IX: "Przepasał czoło skórzaną opaską". - "skórzana opaska" literally means "leather band".
I doubt that Sapkowski has made any sketches, the closest to his vision of Geralt is probably the W1 Geralt. The game was made with conjunction with him, and that version of Gerry is a perfect match to the one described in the books, tho his personality is captured way better in W3
Is there anyway the headband could be turned into a useable item, like the Spectacles from HoS, or the Masks. I saw a similar mod on Nexus that does this, though that uses a different Headband, and I prefer the look of this headband, and I think it would look very good with the shorter hairstyles.
This doesn't appear to work with Nvidia Hairworks, and the draw distance on it is really short. Is there any way to fix this? There are many cutscenes where the camera zooms far enough away for the headband to dissapear and Geralts hair to become extremely low-poly, so it breaks immersion a bit sometimes.
