光线追踪最适合使用什么类型的几何定义文件格式来包含材质的类型

我想使用 .obj 格式，但我注意到它没有表示材质的类型，即不透明，透明，反射。是否有一种通用的文件格式也包含这些信息，或者我应该只使用已知的 .obj 格式并进行更改，以便它包含该信息？

I wanted to use .obj format, but I noticed that it doesn't have representation for the type of material, i.e. opaque, transparent, reflective. Is there a common file format that includes that information as well, or should I just take the known .obj format and change it so that it'll include that info?
