Here buddy! At any moment that you wish you may contact me, to implement something. I use godot engine, 100% free to use without payment any above $100.000,00 like Unity. You can receive 1 billion dollars, if possible, and even thus you pay only you want, - no obligations like Unity. This one makes proper export linux files in Opengl. It's a argentine engine. Amazing engine. It have thirty years-old, so a quite solid engine. Accept GDScript (native) and C#(sharp). https://docs.godotengine.org/es/stable/tutorials/3d/introduction_to_3d.html
