Windows going black for no reason

Greetings devs,

I made a few windows for a map I’m working on, and despite applying the following changes

Transparency → .37
Material → Glass
Color → Fog

It still looks different that how I set it to, nor is transparency working one bit.

That was a video that proves me showing what adjustments I make to a part to become that.

However, I have made absolutely zero changes to the windows ever since I finished them. This was a photo at the time of window completion. All clear.

That’s because fog is pretty broken. Use atmosphere.

Where is the atmosphere property? Cause I don’t recall ever modifying it.

You need to add it in the lighting instance.

Turn off unified lighting in beta features

These were the following properties I found it as. What changes should I make to it?

That works perfectly. I appreciate you both helping me too!
