It's time to set breakpoints in related methods and then step through the breaking of your block in the test case that baffles you.

At this point I already managed to get getActuallState to work (I said it a few posts above).

So now getActualState method is called and the correct value is returned. But the model of block isn't changing until I'll force a block update. If I'll try to break block, it will emit particles with the correct texture.

So the game just doesn't want to.. redraw block?

The chunk will redraw any time the state saved to metadata changes, but not when the actual state changes (because the actual state could change at any time). You need to call World#notifyBlockUpdate to trigger a chunk redraw.

 

Since there's no callback for blocks n positions above a block changing, you'll need to periodically check whether the block can see the sky and redraw the chunk if that changes. Since you need to store this somewhere and redraw the chunk when it changes, you may as well store in the metadata rather than setting it from the actual state.

 

Depending on how frequently you want to check this, you can either use a TileEntity that implements ITickable or schedule block updates (override Block#updateTick to perform the check and call World#scheduleUpdate from Block#onBlockAdded and Block#updateTick).

I still like the randomness of ticking the block like a crop waiting to grow.
