I'm trying to use an orthographic camera, and it makes the FBO repeat itself on the screen. Any ideas on how to go about fixing this? I will eventually be making an orthographic camera using raw matrices.

	glClearBufferfv(GL_COLOR, 1, black);
	glClearBufferfv(GL_DEPTH, 0, &one);

	glUniform1f(uniforms.render.shading_level, show_shading ? (show_ao ? 0.7f : 1.0f) : 0.0f);
