Always weird borders between Effect Mesh(WALL_FACE,CEILING,FLOOR.etc)

Hi~
I am developing an app with Quest 3 in unity,after I scanned my room in Quest 3, I attached a standard material to the scanned mesh(WALL_FACE,CEILING,and FLOOR) ,it seems that there are always some borders between the scanned mesh.To solve this,I scanned my room again and again, but borders just exists all the time with different width.
How could I fix this?

I think this is a Meta side issue. You could try to post your question on the Meta forum here: https://communityforums.atmeta.com/t5/VR-Forums/ct-p/discussions

Thanks for your reply.I tried it, but haven’t got any solutions to that bug.
