Isaac Sim mistakes transparent bottles for floor in segmentation image

Hi there,

I was collecting data using the Isaac Sim in our own environment and found that the transparent bottles were mistaken for floor but the opaque wine bottles were correctly recognised as bottles. Please see the attached images.
The names of those transparent bottles in Unreal Engine are just bottle+number.
This is a bit annoying. Could you please help with this issue?
Thank you.

Kind regards,

Hi Xmaster,

This is probably because the ray passes through the transparent bottle.
Let me discuss this with our team.
