RCD-RUST OFFSHORE LAB ENTRANCE V1 BY PRAVUM 1.0.0

about adjusting the right height, wouldn't it be quicker to simply save it with Y = 0 when you save your prefabs? I see that often, this would ease the process...

and the underwater rock formations have loots on them, instead of the arid ones you used here... they do not have the same structure tho, so it may be only because your choice... 

good luck, this one I wanted to see and buy since the labs are out!

also, if you want to make things a bit more challenging, if you stick "Underwater Lab A/B/C or D" to your monument, when you generate Underwater Labs in RustEdit, it will generate a Lab on its own... and the more you call the function, the bigger is the lab *(X3 max)

I did not test it with your monument, but with my own it's working well
