Reflection Probes Are Broken Under iOS and WebGL

Has anyone had any success with reflection probes on mobile or in the browser?

Here are the type of results I see:


In the Editor



On iOS (iPad Mini Retina)



On WebGL (Firefox)

 

I've found a temporary work-around, using the code from this blog

http://www.vadim-maltsev.com/blog/2014/9/24/unity-5-real-time-reflections

The code involves the use of a custom reflective probes, reflective shaders, and a custom script.

 

I can't get real-time reflection probes to work on IOS (Pro) either. Is this a feature that is supposed to work, Unity?

 

With the same settings above, same problems

Runs fine on a Mac



Still broken on WebGL (5 minute build)



and iOS of course (OpenGL ES, compiled with Mono 2.x to avoid long wait)

 

Either @Kuba, @SpiriTx or @KEngelstoft, (in reference to this thread) in which version of Unity will the issue of real time reflection probes on iOS and WebGL be addressed?

Thanks.

 

Hmm, I'm also having issues with reflection probes on iOS. In the editor they look fine, but when I deploy to iOS I get a very strange faceting effect on the model (which is the unity default sphere here). Occasionally the cubemap seems to flick to black (on some quads) as well.

In the Editor:


On iOS (strange facets):


On iOS (black flickering):


The facets almost look as though smooth normals haven't been used, when clearly they are being used in the editor. All this being said, the probes do appear to be otherwise reflecting correctly. If I find out the cause I'll be sure to post.

EDIT: After more testing, it's become clear that the facets and black sections aren't related to the model's geometry, they're caused by the cubemap (I've since tried with different resolution spheres and looked at them from different angles, and the facets roll over the surface).

EDIT#2: Upgraded to U5.02 and everything works perfectly!

 

I upgraded to 5.02 a just a moment ago. Same problem. Baked reflection probes are still working across different platforms with a variety of skyboxes, but real-time (per-frame) reflections are still broken on iOS (no reflections at all) and WebGL (artifacts).

 

This still seems to be plaguing WebGL in 5.2.1. Any update or workarounds?

 

Same problem... No way to solve! I am compile on WebGL. Unity 5.2.1 and Unity 5.3 Beta...

 

Did you get the work around to work on WebGL? I attempted this solution, but it still does not work on WebGL?

 

Unfortunately no, it didn't work with WebGL, and WebGL builds generally appear to have more problems in 5.2 than 5.1, but the code works on PC and iOS (albeit with not-so-good performance).

 

Sigh...I wish there was a better timeline for when this will be working in WebGL. Unity's roadmap doesn't have a date for this either. It only mentions they are working on WebGL 2.0 support.

 

I have the same problem on WebGL and iOS build, but iOS build has close to 0 artifacts and WebGL has a lot.
We really invested a lot of time to make sure our project works on IL2CPP, please fix this.

 

Has anyone found another alternative to getting Reflection Probes and GI running properly in WebGL or mobile in Unity 5 (5.2)? Or at least recreated the functionality through another means?

 

I am also interested by this as I am facing same issues. Reflection probes are not working correctly on WebGL using Unity 5.3.0f1.

 

I was having this issue as well with a StandardSpecular surface shader in OpenGL mode so I went digging through the builtin shaders source and found this on all their passes:

#pragma target 3.0
// TEMPORARY: GLES2.0 temporarily disabled to prevent errors spam on devices without textureCubeLodEXT

when I added '#pragma target 3.0' the issue seemed to be resolved. I hope this helps.

 

#pragma target 3.0 is already there. Maybe you mean #pragma target 2.0?

 

Can anyone confirm if this issue is fixed in Unity 5.3?

 

No, it's not. But I have good news. The bug report I filled on this just got confirmed, so we can hope it will get resolved.

 

Bad news. Just got the answer:

 

Regarding the Reflection Probe for iOS that by default iOS is set to "Simple" in QualitySetting window which the Realtime Reflection Probe toggle is disabled.

So just set the iOS to "Better" (or higher quality) or enabled the Realtime Reflection Probe in Simple setting, that should make the Reflection Probe works in iOS. I know it is little tricky.

 

In that quote you you quote someone saying

I'm not sure what that means really... Does that mean you cannot have reflective materials in WebGL? If not do you know what settings I need to set and where to make them work? I cannot see any settings anywhere about 'Smooth' reflections...

 

@visoft.tov Did you ever find out exactly what *smooth* reflections are, and how to enable/disable them? In your understanding, if my reflecting object is just a flat surface, should this work? Thanks!

 

Hello. Unity could you confirm that realtime reflection probes is not working/not supported in WebGL platform right now? Or it is a bug. I had the same bugs in 2019 LTS right now.
In Unity 5 this bug (https://issuetracker.unity3d.com/issues/webgl-realtime-reflection-probes-dont-work-only-baked) was closed as By Design. But there is not clear information in documentation about this. The only info I see is here
https://docs.unity3d.com/Manual/webgl-graphics.html
It said that WebGL should support real-time reflection probes in webgl.

Same bug was reported here
https://answers.unity.com/questions/1534418/reflection-probe-failing-to-reflect-in-webgl.html

Could you clarify, is it supported or not. And if supported when it will be fixed and in what version? Thanks.
