Hey len_xie ,

Giving the geometry thickness (e.g. by poly extruding) will resolve the issue in the current scene. I'll check with the developers to see if there is a way for us to handle such cases automatically - it seems that the first refraction hit is ignored when a volumetric is intersected after it.

Best regards!
