I have a two block high techne block model with a gui. But i can only open the gui using the bottom block of the of the model and I can only break the model using the bottom block. I hope i explained this correctly. Thanks

That isn't a bug.  It is a feature.

 

You need to chance the size of the bounding box for the block.

I changed the bounding box size and made it two blocks high. Now the top block of the model is solid and i can no longer walk through it, but still if i left click the top block of the model it wont break and it still wont open the gui. Thanks for the reply though.

Are you sure you changed it correctly on both client and server?

I'm having the same issue

Use two blocks. Like door.

A simple tip for having 2 blocks with 1 tileEntity.

world.getTileEntity(x, y-1, z);
