alpha 0.09 added instance caching back, blocks should place 5x faster cave generation + placing time optimized from 10k blocks/s to 20k when i added instance caching in the previous updates, there was holes/missing blocks in caves, but now i brought it back and fixed it and its safe to assume that there are no holes/missing blocks in caves anymore when i explored 10 caves with 2k blocks and over. fixed player falling out of the map when cave is not done replicating to the player's client update 0.095: i thought of a way to get my cave gen faster when i was sleeping. the way is changing from depth first search to breadth first search 3d fill algorithm. now the block generate(not the block placing) speed went from 40k block/s to 200k block/s(5x generate speed!)
