Alpha issue

So how do I make it to where the alpha will return to 100 after a player leaves that object?

Can you use a raycast for this? Just check the distance with a raycast, and if it’s not close then set the alpha to 100.

Cool, but it’s only sending it in one direction

If you need it in every direction, you’ll probably need to use a Switch block, and turn it on with a Proximity trigger, and then off with a timer.
