UPDATE 12/30/2011 Added an updated version of the armor which adds the purple kilt back in, with new hi-res texture. This had been requested by a few people and I think it was a good idea.. thanks to those who brought it to my attention!
Please note that only the dwarven armor texture is included in the Royal Heroic Armor file, so if you want it you'll need to install the main file and then overwrite the armor files with the Royal Heroic ones
While I was making that change, I took the opportunity to correct a couple of oversights; there were a couple spots on the armor where the original lower res textures were not modified and I went ahead and corrected that. This is probably most noticeable on the upper arms, where I've created a scaled look to replace the kind of muddied pseudo-chain of the vanilla texture.
I've been working on this for the last week or so; thanks to everyone who helped with comments and criticism along the way.
It started out as just a recoloring of the dwarven arrows and kind of snowballed. Now it is a full hi-res replacement of all things Dwemer with versions that try to put forth a more gleaming, heroic appearance than the vanilla textures.
I know it won't be for everyone, as it doesn't keep with the downtrodden, dirty look and feel that much of Skyrim has. That's cool with me.. I just hope that some people do find it helpful and fun.
Working on a similar treatment of the Orcish set now, so if you like the heroic dwarven armor and weapons then stay tuned!
