Texture / Lighting Glitches between Flan's Mod: Reloaded and BBS Mod (Forge 1.20.1)

[BluGreenInc]

Depending on the angle I look at BBS's model block with either an image morph or a model with a flat body part, the lighting goes like this https://kappa.lol/1JbDu, and from this angle it's normal https://kappa.lol/uNKXI. This is what happens with models with flat body parts: https://kappa.lol/T6kO5 https://kappa.lol/qavGw. Everything is normal without flans mod installed.

PS: BBS Mod is a fabric mod but I am using it with Sinytra Connector.
