everytime u do the cmd /door it gives u a wood log how do i change it to a different block

easy u create a new block with the name door

There are a few door blocks that come with MCGalaxy by default. To see all of them, do /search blocks door
So for example, if you wanted an obsidian door, you'd do /door_obsidian
Not every single block has a door version though. For example, custom blocks you add will not have a door version. To turn a custom block into a door, you must do:
(os map) /os blockprops [block id] door true
(local to a single map) /blockprops level [block id] door true
(global to the entire server) /blockprops global [block id] door true
