UnrealEngine compatibility with OpenGL
I can only imagine UnrealEngine built using OpenGL. And even though I'm not sure it is made using OpenGL I really don't know any other way of making a program like this one, so... What kind of support does it allow for OpenGL ?
Or to be more precise... How and it which cases can I use OpenGL in my code ?
PS: I tried to use GLColor3f and GLColor4f instead of FColor, but it didn't work. Maybe because I need to include something ? What ? I want to know !
Unless you are modifying the engine itself, you do not touch the low level stuff directly. That is, for rendering or input handling, you must try to do it through the Unreal Engine framework. The framework handles the low level stuff and calling the actual OpenGL or DirectX calls. GLColor3f is an OpenGL construct and Framework funcitons wont accept that.
So if you are not modifying your engine, you should stick with what the Engine framework has given you, in this case Fcolor
