in theory, you can have moving ladders,
but there are snags, you don't move with the ladder just to name one
its actually the
skin
value that determines
what tha brush is, not the entity, valid ones are : ladder, water etc.. these have numbers like : -16
to use this
turn smartedit off, and add the skin key with the corresponding value
This is not a "new" discovery, if anyone bothered to read tommy14's tuts and the A.M. boards at the verc, you would have known this a loooong time ago
and some randomness:
moving climable ropes
