Answered: LiveLink doesn't generate material instances for custom materials created in Mixer

Unreal Engine 4's Livelink doesn't generate material instances for custom materials created in Mixer, I've tried reinstalling the plugin but that does nothing for me. All texture maps are importing fine, so I've just been hooking everything up manually but after seeing the plugin is supposed to do that automatically it made me think I'm missing something. Am I overlooking something simple or perhaps there's an easy fix for this I'm not aware of? I export all texture maps when saving to the bridge.
