Well, playing around in hammer, getting my Prefab for a lava hazard working. I got the door opening working, and I moved it to my current map project... and the first thing it does is fail. I made sure all components were accounted for, which they were. and it gets stuck on while trying to open, and instantly closing. Also, how can I set a specific distance to raise my door? edit: right after I posted, it started working (it was catching on the viewable side of a no draw), but the other issue remains, how to make it not.
