I made a playground that calculates the angle between north and normal vector of clicked mesh:
when you click somewhere on red box or black sphere it’s gonna show you the angle in the middle at the top of the screen.
My question is if can color full plane of clicked mesh, photo below for better understanding. I tried to use decal(44-53) but it draws on full mesh I mean it covers also other planes of this box.
so the side of the box was clicked and it changed color to yellow:
almost got it
