Can I let a mask follow a directional light for instance i build a mask that blends between city night lights on a planet and day time. now i want the directional shadow light to follow my mask. meaning if i change the directional light the mask follows. any input would be great.
I think it can't be done only with material, cause you don't have access to the light vector. But you can make a blueprint, and there you can measure the light's rotation, and adjust the mask position based on it.
