Do I need to normalize the overlap?

[laserbeak]

Hi,
When I create my overlaps, I get something very different from “ACTIVATED”/“DEACTIVATED” when walking on pressure pads. I’m wondering if I need to do some sort of normalization like we had to do with the vectors?

The code looks OK but check against the end of lecture code to be sure. I suspect it is a setting on the collision of the Blueprint that is the issue and the best way to find that is rewatch the video and check all your settings.
