Two questions on environment/reflection probes

Unity Engine
1

Hi there,

First, I’d like to just simply have one environment probe in my scene that is attached to my AR object. I’m using the ‘MakeAppearOnPlane’ function so the model is always static. I’m currently finding that with automatic placement, the reflections are not reliable enough when it comes to actually affecting the model. Plus With the model being static I guess it’ll be computationally cheeper just to have one probe.

Secondly: I’m finding that on iOS (haven’t tested Android as I don’t have a device yet) that the probes effect on the model is very exaggerated, the materials do not ‘reflect’ how they are setup to be. If I add my own hdri and remove the environment probes then everything appears as it should.

Any help on these points would be much appreciated

Automatic environment probe placement may be disabled by setting the [AREnvironmentProbeManager.automaticPlacement](https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@latest?subfolder=/api/UnityEngine.XR.ARFoundation.AREnvironmentProbeManager.html) property to false.

You can manually add environment probes positioned and sized wherever you wish using the [AREnvironmentProbeManager.AddEnvironmentProbe()](https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@latest?subfolder=/api/UnityEngine.XR.ARFoundation.AREnvironmentProbeManager.html) method, if subsystem descriptor reports that manual placement is supported.

What does it depend on? Platform? Phone model?

Manually placed environment probes currently are only supported on ARKit devices running iOS 12.0 and later.
