Does the glass of this window have any magic of refraction?
![kyoreona](https://delorean.daz3d.com/forums/uploads/userpics/761/nFUZQSM8E7XXI.jpg)
I rendered an image of the outside of the room looking into the inside through a window.
The first image, before rendering
The second image, the hidden wall, the rendering, everything is normal, everything is as I expected
The third picture, which does not hide the wall, render, and reflect the scene in the window, does not belong to the scene that can be seen from a normal Angle.
I don't understand, for the first time in the DAZ encountered this kind of enchanted window

Looks like regular refraction to me, the the IoR might be a bit too high. Where do you have it set now?
thank you ! I found it ! surface,[refraction index] ,set it to 1,everything goes right !!
Refraction index of 1 is air.
I think your problem might be that you should have set thin film to On, assuming that your glass is a thin plane, and not with volume.
I'm sorry, where can I find the options you mentioned![surprise surprise](https://www.daz3d.com/forums/plugins/ckeditor/js/ckeditor/plugins/smiley/images/omg_smile.png)
Felis misspoke; you're looking for thin-walled, not thin film. It's under Volume:
