Grettings!
I need some advice about Game Engines.
Look, actually I'm programming a Rhythm game and, generally, I used OpenGL/DirectX (with selectable option) drawing primitives to do it in C++. I want to build also a "Story Mode" with a simple world that needs vertices/animations/world/etc coming from a 3D editor (like blender/3DS/etc).
I need to know about a Game Engine or some libraries that can do that but only when the user request the story mode. There's some solutions for that:
1. Use a game engine and ignore ALL the drawing I used to do the rhythm game and use the new one. (I don't want to... )
2. Find a Game Engine loadable by demand, but I need also to draw using draw primitives using DirectX/OpenGL.
3. Not use a Game engine and build my own. But, there is a library for helping to do this?
Can you help me? If a solution for this is something that not involve game engines... is ok :)
