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.

All you have to do is to pass the images to the shader with its SetTexture function.
