I decided to try my hand a BLB modeling and exporting and came out with this
There are 3 bricks and one item
Have fun! I hope to see these add-ons on many servers in the future!
-Bricks-Here are a couple of bricks that I made from the legend of zelda
-Crystal Switch

It is the same size as 2 2x2 bricks
Only the inside is colorable:
Download-Hookshot Target
it is the same size as a 2 1x2 bricks on top of each other
same as the crystal switch, only the center can be colored
Download-Lock
Works like the default doors: one click open, one click closed
The brick is the same size as a JVS door. The collision for a locked lock is the same as a
JVS door. The collision for an unlocked door is one 1x4 plate (dont worry; you can still walk through 1x4x5 doorways!)
Locked:

Unlocked

Can be colored:

-Items-Brick Specific Hookshot

Looks no different than the other hookshot;
the big difference is how it works.
This hookshot will
only pull you towards bricks named hookbrick.

All the bricks were made with badspot's Obj2Blb and Milkshape
