Hello all, I ran into the same roadblock trying to export WebGL from Unity, ONLY works on Firefox on mac/PC. iOS NG. File sizes are large. So I tried (today) to see if UE would be the solution, it was worse and the basic FPS shooter project weighed in at 500 MB! in the HTML5 folder. All kinds of errors trying to play. So, I returned to Playcanvas.com, it’s the closest thing to using Unity to develop and instantly you see your final published demo (game/etc.) in another web browser window, no compiling. The catch is you now have to bone up on the pure version of Javascript if you want to go beyond the many sample scripts available. You will have to export all your meshes as FBX (which you probably did already to get into UE) and upload to playcanvas editor. There is a short learning curve on using interface and it works with PBS and HDR lighting, very nice output with small file sizes. End product is either a link to your playcanvas account (free) or you can pay $15/$50 a month to have more control and download your projects as a self running package (well, actually the package has to be hosted on your webserver to run). Check it out-you won’t be dissapointed. good luck,
