Ok I'm looking at the materia slots again... they aren't circular... but that's because the original slot icons weren't and I followed them to the pixel... I'm changing the glare a little to make the originals look a little rounder, and I'm making a second, circular set. the circular set will have to be a larger aspect ratio in order to gt the same effect... (which I think is why the originals were more square...)
I'll post the results shortly... hopefully I won't have to make sl do too much more swapping...
