Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Does UE4 support HTML5 with WebGL on smartphones?

Does UE4 support HTML5 with WebGL on smartphones? If so how can I package project to support on them. As I see UE4 using large amount of RAM in browsers and tab crashed when I tried to load game. For example I want to play ShooterGame or run Realistic Rendering on Galaxy S5. Is that possible? I don't need all features with materials and texturing, I just want view geometry. And I want to load game as fast as possible in my tab. That improvements are planned?


Product Version: UE 4.13

HTML5 is supported for web browsers but not mobile devices. You can package for Android or iOS if you'd like to have a game on your tablet.

We're always in the process of bettering our engine. It takes time to implement better features across all platforms, so patience is needed.

Any update on the current state of HTML5 support on mobile browsers? We are currently working on a proof of concept that works on HTML5 and can sort of get it working on HTML5 lacking textures, however this may be due to packaging config and project settings.

Currently the limiting factor for using HTML5 exports on mobile browsers is the amount of consumed memory. There are two features coming in to web specs space that will help cut down memory usage: AudioWorklets (https://github.com/WebAudio/web-audio-api/wiki/AudioWorklet-IDL-Proposal) and multithreading support in WebAssembly (https://github.com/WebAssembly/design/issues/1073). These help reduce the needed memory that UE4 will need by improving audio and filesystem utilization, though it will take a bit of time until browsers have them (current ETA for developers is later this year)
