Pre-Splicer the Boots of the Emperor's Agent used to react in a different way to shaders. The metal part of the pants used to turn one colour, and the fabric/leather parts another (as usual).
The shader I'm using (burnished orchid) usually turns the metal green and the rest white as can be seen on the arms. Now it just turns the pants completely green? As if the pants are completely made out of metal. Any other shader I apply too just turns it all into a single colour.
