Scans the avatar for duplicate materials and replaces them with references to the same one, useful if you're using VRCFury together with AvatarOptimizer's Merge Skinned Mesh. Makes use of ndmf, so all modifications are non-destructive. But still: Remember to take regular backups of your project.
Add the MaterialDeduplicator component to the root and it will run when you build your avi.
The component also displays a prediction for how it will try to deduplicate the materials This gets recalculated at build time due to other plugins making changes beforehand.
This ndmf plugin is written as a replacement replicating the same functionality as NdmfVRCFReorder in a way that isn't dependent on a bunch of reflection.
This will help it break less often and doesn't change the behavior of other plugins.
NdmfVRCFReorder was orignally written because VRCFury creates a seperate material for each skinned mesh, which makes AvatarOptimizers's mesh join tool unable to merge the materials.
