#anyway when the game starts" but what you're not considering is that for ease of placement the model will probably

#always be given an offset from the root nodes position so as youre placing it in the editor its not clipping through
|
|
#the ground, and some items might be given more or less of this vertical offset, if we do it at runtime by actually
|
|
#checking where the ground is, you dont need to fuck around with this offset at the scene level, you just adjust
|
|
#the script variable and the item can figure itself out, yeah its fancy but its also a nice creature comfort.
