Hatch problem

[Chap]

if you're using planes as a ceiling or floor around the hatch you need to be careful that they don't collide with the hatches collision mesh. I had some problem like this in the past but you just need to make sure that the planes stop no further that the model of the hatch.

Also have you tried opening the hatch to see if it's location actually allows it to open? You could just place a spawn in the room above the hatch and try opening it from above to see if it'll swing open or not, if it doesn't just try moving the surrounding objects about a bit. GL!
