These two models also need Arktoon's shader v1.0.2.6 and Poiyomi's shader, you DO NOT NEED the pro version of it, the "Toon" version is the one to be used here, and is completely free. These models uses Poiyomi's toon version 7.3 AND 8.1, i personally used the version called "poi_Toon_7.3.50_To_8.1.167" (Released on the 27th July 2023), that you can find on Poiyomi's discord server.
