Not sure if this is the right place, but have you considered introducing 2D directional light and something like shadow falloff/cookie?

Let me explain the question/use case:

Right now, all the lights basically behave like point lights when it comes to normal mapping and shadows. Even freeform light shines from pivot spot, so that the shadow has always the direction from pivot of the light to shadow caster (though extended further from shadowcaster), wherever it might be. That doesn't feel very well when it comes to natural light sources which are supposed to be so far away that the shadow casting angle is basically constant, just like 3D directional light works. The same goes for the normals, which are lit from the direction of the pivot spot of the light. So currently there's no way to apply "daylight" on your normal mapped sprites, at least without excessive use of unnecessary amount of lights

The shadow falloff/cookie is meant especially for top-down projects where you can use them as sort of drop shadows extended from shadowcaster, but not for the whole length of the light, but just for preset amount. Or is there any dedicated drop shadow system for top-down projects in development?

Thanks in advance!

I see there never has been an answer to your question about the direction of freeform lights. Did you ever find another solution for this? It would be nice if you could set the direction of the light. For example if you have a door with light shining through it you would want the shadows always going in the same direction, but freeform lights now cast shadows away from one point which looks realy weird.
