No matter how I tweak my characters skill points and dump them in craft armor/craft weapon, I have zero options on the radial menu to mod the helmet and shield appearances (yes the items are equipped). I also have no option for changing colors on anything (armor, cloak, weapon, shield, helmet).

I have not added any custom haks/mods/texturepacks to the game.

Do these features even exist in NWN:EE or 'Enhanced Edition' secret code for worse edition?

Running v78.8186

Any help would be appreciated.

Thanks.

The ability should be in Special Abilities -> Crafting Skills (or something like that, I have only Polish version of NWN currently installed) once you open radial menu by right clicking on your character. It should bring up a dialogue window, which allows you to craft and modify weapons and armors. I doubt they modified this element in EE, because it's basically the same game with very little changes.

I don't have an option to modify the helmet as well in the Diamond Edition, but I never invested in crafting skills, so this might be the case. GOG support won't help you with this I presume, because the problem is strictly gameplay related. Your best shot will be to contact Beamdog, if you're certain that in the past there was an option to modify these elements: https://beamdog.zendesk.com/hc/en-us/requests/new.
