My custom bricks are invisible

[Parallax]

So I've been trying to make some custom bricks. Problem is they don't appear as a ghost and don't appear when placed.
The console says they're too small... But I've tried making some larger bricks but they still don't co-operate.

Well... we need more info than that to find the problem. Give us a console.log and the brick files. How are you trying to make the bricks? Manually or with an obj to blb converter or what?
