How to make reflection probes work correctly？

[wilson]

I am learning how to use reflection probes，My steps are as follows：

1. Create a box
2. Create a sphere
3. Create a probe
4. Add sphere to probe’s renderList
5. Set probe’s cubeTexture as box’s reflectionTexture

Now, as PG shows：

My confusion is：When the camera is far away, The reflected ball did not decrease in size，Did I use it incorrectly?

Looking forward to your help

I think this answer should help you:

Reflection probe for refractions behaving like reflections when scene useRightHandedSystem

This magnification is not because of the IOR but because you are using a probe, which by default is supposed to represent the geometry at infinite distance. You should use a local probe (cube map) instead, if you want a more localized render. To convert a cube map to a local cube map, you must set the boundingBoxPosition and boundingBoxSize properties. For example:

We also have this sample using local cube maps:

Thank you very much. This has been very helpful to me
