    i use reflection probe in webgl, but the result is very diffent in editor and browser

    unity version 5.1.1f1
    [ in editor ]
    editor.png

    [ in firfox 40.0.3 ]
    webgl.png

    [ in chrome 47.0.2508.0 (64-bit) ]
    webgl-chrome.png

    [ here is my code ]
    Vector3 newPos = new Vector3(centerPosition.x, 1.071f, centerPosition.z);
    GameObject probeGameObject = new GameObject("reflectionProbe");

    probeGameObject.transform.position = newPos;

    ReflectionProbe probeComponent = probeGameObject.AddComponent<ReflectionProbe>() as ReflectionProbe;

    probeComponent.mode = UnityEngine.Rendering.ReflectionProbeMode.Realtime;
    probeComponent.refreshMode = UnityEngine.Rendering.ReflectionProbeRefreshMode.EveryFrame;
    probeComponent.timeSlicingMode = UnityEngine.Rendering.ReflectionProbeTimeSlicingMode.NoTimeSlicing;
    probeComponent.boxProjection = true;
    probeComponent.size = new Vector3(10, 10, 10);
    probeComponent.resolution = 256;

    【question 】
    dose webgl support reflection probe or which version can support？if so ,how to get correct result like in editor

    It's not totally unexpected but it is definitely a bug :)

    - do you get any error in the browser log ?
    - Is it the same with 5.2?

    if you could submit a bug report with your project that would be great.

    yes ,it is the same with 5.2

    Warning: Rendering to mipmap levels other than zero is not supported on this device

    Error: WebGL: A texture is going to be rendered as if it were black, as per the OpenGL ES 2.0.24 spec section 3.8.2, because it is a cube map texture, with a minification filter not requiring a mipmap, and is not cube complete (as defined in section 3.7.10).

    That error message is currently shown more often then it should be, and can be ignored most of the times.

    This will be fixed in 5.3.

    The second error does look like it may be related to the problem. But, as @Marco Trivellato wrote, please file a bug report with a repro case, and post the case number here - then we can take a look and figure out what is going on.

    has this been worked out? i'm just about to release a webgl game, but the standard asset shader "glass bump/distort..." is flickering between black and its normal state. I've tested on both mac and windows with chrome, safari and firefox. Weird thing is... only seems to happen on firefox while using windows. Also mouse input is bizarre on firefox+windows, but fine everywhere else. I figure it's a bug.

    There seems to be a bug in Firefox, thought I need to check whether that is Windows-specific or not.

    Have you submitted a bug report ? If so, what's the bug number ?

    Hi there, I am using Unity 5.4.1p3 and when I am creating a reflection probe in WebGL on Chrome and Firefox I am having this warning : Warning: Rendering to mipmap levels other than zero is not supported on this device

    Is this a normal behaviour ? Is there a way to avoid that ? @Marco-Trivellato @jonas-echterhoff

    Thanks a lot.

    This is expected. See https://docs.unity3d.com/Manual/webgl-graphics.html:
