three.js cannot show transmissive surfaces through other transmissive surfaces – this is a limitation of our current realtime approximation of the technique. To support that appearance you’ll need to use other methods like alpha blending or alpha hashing.
Thank you for your reply
Perhaps I can use alpha blending, but it will cause the object to lose or weaken its physical properties, such as refraction and reflection
I learned on GitHub that ray tracing technology may be required, which is complex and has poor performance. Currently, I feel that there may not be a good solution available
