Thanks for your contribution, which is totally right in most points.
But folks, don’t worry in this case: as far as my experience and research allow, the development philosophy behind Coppercube is very user and community friendly.
Coppercube comes from Nikolaus Gebhardt the main developer of the open source realtime engine “3D Irrlicht engine”.
So I guess, we are not talking about money hungry game development system providers who make their users dependent with aggressive DRM “features”, various subscription models and so on.
Admittedly talking about later versions that keep up to date could be more strict in everything. But with Coppercube 6 you get a great simple to use free 3D game development engine with a full set of features now that once downloaded, no one can ever take away from you or prune in the future.
Besides, let’s take a close look at Coppercube 6 Free vs. Pro comparison:
The Pro version offers only four comparatively unimportant additional features, that don’t come with the free version:
1.) post processing effects? -> your scenes can also look amazing without this with the Free version
2.) video playback? -> nothing a 3d game needs primarily in-game, there are also workarounds for this with animated textures or external solutions
3.) customizable loading screen logo? -> lots of commercial Unity projects show the Unity splash screen at the beginning, so no show stopper here
4.) command line interface? who needs this as a mainly no-coding Coppercube user?
Conclusion: Coppercube Free really offers all you need. If you should need the mentioned 4 additional Pro features most users won’t, these days you can get them for only 26 EUR as a little support for such a great software and developer.
Godot is of course a real free and promising great project, but in my experience still not easy to use without proper programming skills. I wish a blender game engine or Godot could offer what I can get out of Coppercube’s simplicity and potential at the moment, but these first ones don’t. Please, have a look at my example project mentioned in my 1st post.
I would also prefer free open source solutions (OS, drivers & software) anytime as long as they exist. So I just wanted to point out Coppercube to inform about it and help out other interested blender users. If someone can name an equivalent free open source alternative to Coppercube, go ahead dear critics.
