I'm not so good with OpenGL stuff so I googled it, then used the forums search, but I did not found any multi-texturing regarding SFML.
What I want to achieve: Render the scene into a RenderImage, then render the light map (dynamic, as light could move, and light-cones even rotate) into an other render image. Then using a shader that combines the two and draws it to the render window.
What I'm asking: How should i set up the second texture so the fragment shader can use it. I know this solution has problems with old hardware, but is there anything else I should pay attention when implementing it? Especially regarding SFML.
Thank you for helping me out.
