This problem was already solved.
I've managed to compile engine code in haxe, using away3d-core-openfl's Stage3D to OpenGL wrapper, but nothing has shown up in the screen.
Only white color is shown in the screen even if I choose different color for clear.What I have drew was not presented in the screen. It looks like opengl is not properly configured for some reason. How can I debug and fix it?
I have already tested the program on gDEBugger. Only thing I know for now is the texture is successfully uploaded to the GPU. I haven't found the cause yet.
