Here, I'll write notes Relevant to Poiyomi on the model.

Rim Lighting

A lot of things have changed in Poiyomi since the release of the model. You'll notice that the rim lighting is very bright. this is because Poiyomi reworked the lighting and the conversion between versions didn't quite work perfectly.

It's an easy fix though, head over to the Rim Lighting section in all the materials and change the blend mode from "Add" to "Mixed"
