I’m not quite following…
My apologies but I actually meant hover instead of hit. When I hover over B (part that isn’t transparent) it changes to it’s hovered color, ovodus button works like a charm on this. Now, I want to achieve the same effect for A, but when I hover the part of A that is behind B, it won’t detect the cursor because B is on top of A.
And about the reference to the other button. The end goal for me using this, is to create a circular menu with different pieces that change dynamically according to the amount of buttons needed.
As u can see in the image attached, there are 6 buttons here. Each button has an image of 1/6 of a circle (in this case) which is also placed in the advanced hit texture slot.
But since each image has a large part (rest of the circle (second image attached)) of transparency, they all overlap with each other. So in this case I can only hover/press button 6, since that’s the last one added and thus the on that’s on top.
So I don’t think I can reference to a specific button, since it could be any of the others…
I hope this example still makes sence… 
Thanks in advance!
