glass installation procedure

hello! I’ve been working in an animation and I’ve had a lot of problems with some things:

the floor and that metallic box have gone crazy and I donnow why.
some parts of the facade are not nitid, while other parts are so clear.
and the glasses have some small dots or something strange.

I need help! thank you so much.

I’d check for duplicate faces…



I thought you would be right but no, there’s only one.
I’ve noticed that it’s only like this when I put setsmooth, I donnow if this would mean something for you?

Select your object go into edit mode. Press “A” to select all vertices then press “Ctrl + N” to recalculate normals.
