Draw custom frame buffer into HUD
Hello Unreal Community,
I am new to Unreal and the basic concepts but quite experienced in C++ coding in other contexts. With Unreal now I would like to draw own user content into what I would like to appear as a HUD. Imagine I have a library able to render content into, say a framebuffer such as Qt.
From what I gather in tutorials and docs I conclude that I need to derive from AHUD and then access the contained UCanvas. My question is: what would be a canonical and neat way to access the underlying buffer itself to write into rather than being limited to draw primitives such as DrawText() or icons? Is the HUD the right thing? Or do I have to look into entirely different concepts such as textures?
If anyone could give me a hint it would help a lot.
edit: I should add that I am OK with being limited to Windows for that. Other platforms are not required right now but I would prefer a solution that works for all.
