Hi there, just starting to renovate my tiny house using this as my 3D design.
I have problem with my up window above kitchen when viewing from below side there is something block my view to the cloud/sunlight. , but from above roof its visible and clear inside.

This one thing blocking my view from sunlight


Viewing from above roof, its clear and visible inside.


This effect made my photo rendering wierd


If you wanna take a look at my file, you can download it here.
I really appreciate if you can show me the clue what is blocking my view from inside.
