I did my Text101 on U3D 5.5, the build process completed, in the build folder, I open the index.html, my browser pop up says it seems your browser does not support Unity WebGL content, tried with IE, Google Chrom, Edage, none of them work. Is there a seperate Web GL player I need to install?
Should work on most of the latest browsers (be sure they are updated)…on a PC or Mac. I’m told WebGL is not ready for Mobile. It works on the latest Firefox on Windows 10 64-bit PC for example.
Or, try someone else’s game (find links in these forums for example) to see if it’s just a problem with your index.html file (and supporting files) or if it is any WebGL game.
