Screenshots of this material have been floating around the forum for a couple months, but I just want to make a thread so it's all consolidated together. I received Hedgehog12 from Nexus Morrowind's permission to convert his made-from-scratch assets used in the Symphony overhaul mod for Morrowind. This has been an extremely, extremely tedious process and wouldn't have been possible without his continued assistance. It's still incomplete and there are bugs to iron out, but I'm going to start posting screenshots and hopefully get closer to packaging all this up soon.
The skeleton used for Morrowind's Flame Atronach is weird and not really compatible with any of Oblivion's, so after a number of failed attempts I opted to just remove H12's models' armor and re-rig it to Oblivion's atronach. There are seven variants with three different flame colors.
