Pokémon Model Ripping Project

[Random Talking Bush]

Hello! Sorry if this isn't the right place, I didn't want to make a thread just to ask a simple question about an error opening the .gfbmdl models. its gmax snorlax if that matters.
I receive an error "--Unknown property: "twoSided" in BodyB00:Physical_Material." Then the mesh of the model does not appear, only the bones.
I saw there was someone who asked basically the same question, but he didn't get an answer. nor did he reply in the thread again whether he figured it out.

My first thought was an issue with a certain texture, but none of them are even named that exactly. So i tried renaming the BodyB texture to the same name, no results. I know in maya the textures assigned don't particularly matter when you import a model, not sure if it's the same with 3dsmax(just downloaded it for a model).
I am running 3ds max 2021, just so whoever sees this knows!

I'm new to porting pokemon models, but I have quite a bit of experience porting models from other games and modding in general, so I promise I won't need my hand held THAT much haha.
Thanks to anyone who reads this, thanks even more if you know how to fix my issue!

Yep, lots of people have been reporting that same issue to me. 3DS Max seemingly changed the way materials are set up via MaxScripting in the most recent versions (2021 specifically, not sure if it also affects 2020 yet), so I'm going to have to download 2021 for myself later and figure out what I need to do in order to fix that issue, since it affects every single one of my scripts.
