[Mobile] How can I improve modulated shadows transparency and softness?


For an AR project I’m using modulated shadows, which look great on the editor preview but on the device they have a very hard edge and the transparency is not right. I know I can adjust the color but I don’t seem to find a way to increase the softness or change the transparency (I’m testing on an iPad Pro, with Mobile HDR enabled). I was digging a bit into the Engine source but I can’t afford to spend more time on it. Any information on this will be very appreciated.
