I made a few tests on Kongregate and it seems there are some issues both in exported projects and iFramed projects.
1. When uploading exported HTML+SWF on Kongregate there is no loading-logo screen and the game is not starting.
2. When uploading exported SWF without HTML file the game loads and starts but there is a problem with bars, both height and width seem to be the problem.
3. When using Kongregate iframe option the game starts loading and then crashes with error on, approximately, 20% of loading.
I did manage to solve this issue
by using 2D program(Construct 2) to iframe Cyberix game with the a plugin so the problem is not a show-stopper but it would be great if a game could be uploaded and played on Kongregate (I haven’t tested uploading on New Grounds and Armor Games) without outside programs.
Much bigger issue for me is the iframe factor.
I realize Cyberix 3D is a free engine and that I have no right to complain, I should be and I am very pleased with the engine and very happy I have found it.
But can Cyberix 3D site cover large numbers of plays by iframe? Successful games on Kongregate reach over 100.000 plays and really successful games have over 1.000.000 plays.
