Talking about breaking blocks and such. I think the way to think of it is as if the maps was played in "Adventure" mode. Where the player can interact with levers and buttons but not to much else.
Nice! I did try to make a mc map once. I even emailed notch for promotion ( And got it ). I failed becouse i had not experience with making layouts and i tried to make a urt map with mc blocks in urt. so i really like that this is actually a minecraft map made in urt. If you need help with some mine...
Nice, i was trying to to this a long time ago. I tried to use textures with animap shaders as part of another shadermap shader. I don't think it worked out well. can't really recall lol.
I can't see why it should not work, tought shaders are not my stringes area.
