Various semi-transparent surfaces don't appear transparent.

Examples include Obj_JerrySwimWear (specifically the Obj_JerryWaterballoon model within) and Fig_SnowGlobe00 (Notably I'm not sure how the transparency for this works in the vanilla game? It lacks an opacity texture, and the opacity parameter is set to 1.)

Some other various examples include Obj_PlazaAmiibo and Obj_Sphere10

Fixed for some of them in latest release (Obj_Sphere10 was using refraction, Obj_JerrySwimWear was probably also using refraction)
