well how do I access a blocks position in the ISmartBlockModel?

ok, but then how would I go about not using a tesr? I don't ever change what I render at a specific location, so how would I do this then?

an IBlockState is still limited by 4 bits am I correct about this? if so how would I ever fit 3 integer's in it?

(I've read about ExtendedBlockState but I've read this only worked on the client side, because you couldn't send more than 4 bits,

I have also read this (http://www.minecraftforge.net/forum/index.php/topic,28714.0.html) but here they use once again an ExtendedBlockState)

if it works, thank you very much.
