I must be missing something totally obvious but how do you re-size individual blocks in vox? When i read the help file it said to look in the top right for the H, L ,W boxes but i dont see any? all i see is the xyz location... what am i missing??

This tripped me up too...

That part of the help file is referring to the object editor, not the map editor. If you double-click an object in the object library, it will open up in a separate editor, where you can adjust its maximum size with the H, L, and W values.

Hope that helps!
