Floor doesn't reflect some of the object?

Hi, I created a reflective floor and reflection probe, but the floor only reflect some of the objects, can someone help me please?

This black colour plane is the floor, we can it reflect the ceiling but the white box doesn’t show?

That’s not exactly how reflection probes work, so it seems normal to me.

What is your setup like? What are you trying to achieve?

In general, reflection probes are not supposed to be an accurate way of reflecting things. They are widely used because they are performant and with a bit of trickery often good enough.

Hi , Thank you for your reply! You’re right I don’t really know how reflection probe work, I did increase the reflection probe box to cover the whole area, and all the reflective object work fine, they reflect all the other object but this white box won’t show in the reflection. But it cast shadow.

Edit: I realise it does reflect the box, but it’s very far away i have to rotate the my view to look for it, but i’m trying to make the white box reflection underneath the white box.

There are two Manual pages available that should give you some insight on how this works:

Ok this is the problem I’m currently facing.
If i dont move my camera, its fine:

If i walk around, the reflection wont actually follow it just stay at the same place.

Yes, because unless you set them, reflection probes don’t update. The capture the environment once and that’s it.

I suggest looking into SSR and the post processing stack. Also read what the reflection probes do.
