Hi there.

For a 2d game I'm creating, I wanted to add some colored lights.
I imagine this could be done the following way:

1) Render the background
---
2) Render the colored lights (sprites) to "layer 1"
3) Render every sprite in the foreground to "layer 2"
4) In combination with the use of gl.glBlendFunc(), render layer 2 on top 
of layer 1,
5) Render the result on top of the background.

However, when looking for a solution to this, I looked at Framebuffers and 
render-to-texture solutions. But none really worked - most likely due to my 
lack of experience with OpenGL.
Any good suggestions? Or code examples/resources, in case of a OpenGL 
solution?

Thanks
