So I’m posting this as a separate question from my [Mobile Materials Bugged Question][1] as it was getting cluttered with more questions appearing, this question deserves a separate space.
Question / Bug Report
So I’ve been using modular shadows for the mobile version of my project. My character is a golf ball with accessories attached as separate meshes. These accessories produce their own separate modular shadow which look strange when they are all stacked together.
A good alternative to this is to set ‘Self Shadow Only’ on for each accessory. While testing this on PC, a black box appears, flickered around my character, the size and angle of the box is the same to where stationary shadow would contained.
Because this was an issue and the stationary lighting on PC looks just fine without Self Shadow Only, I set up having the checkbox only set if the platform was mobile.
– On a side note, there is no way to set any of the advanced lighting checkboxes within the blueprint. My solution to that is to make a separate blueprint with an empty static mesh inside, with Self Shadow Only checked and to have the golf ball spawn this blueprint instead of a normal static mesh.
After all this was set up, when it came to testing on mobile a similar experience to the black box occured but it was the shadows that aren’t meant to be cast, flickering behind the ball, -Depending what way you look at it. They don’t seem to be their correct location if the checkbox was disabled, it looks more like a map of all the shadows being placed randomly on surfaces around the ball.
