Html5 Reflections Problems
I am building for HTML5, and I can't seem to get good reflections. The screen space reflection that works for non-mobile/HTML5 builds doesn't work. Additionally, the Box and Sphere reflection captures seem to have the following limitations for HTML5.
My questions are the following. How do I get decent reflections for HTML5? It looks like the reflection captures are taken with an enormous capture radius... is there any way to make smaller captures or captures that are sharper, with a smaller capture radius, or more detailed, and less blurry?
I'm considering switching to Unity 5, because their webgl build of Angry Bots has functional SSR, so I know good reflections are possible in HTML5. EPIC: why are Unreal's HTML5 reflections so poor? or have I missed a way to do them properly?

I have heard back from our developers and you are able to improve the resolution by increasing GReflectionCaptureSize, which will also increase the memory load too. You can learn more here. I also wanted to advise you that there isn't much else that can be done at this time due to the way that ES2 works.
I hope this information helps answer some of the questions you had, have a great day and thank you for your patience. :)

Here is an AnswerHub post which is similar to what you're asking about. This reflection issue has been reported to our developers through Jira, which would be referred to as: UE-11730. This specific issue has not been resolved yet.
You can change the radius of the reflection capture by selecting the reflection capture within the World Outliner. Then you'll want to look within the Details panel and expand the Reflection Capture section. You can then change the influence radius, as well as the brightness, then you would simply update captures.
If you have any further questions, please reply back and we will assist you further. Thanks! :)
