So far I've fixed a bunch of little things like the names above heads being misaligned and some transparency sorting issues.
I've also gotten emitters working with the exact same parameters as blockland and made a script to export emitter (and particle) datablocks to a file as lua script for instant importing into my game.
That means that particles, emitters, brick types, and save files can all be imported into my game from Blockland so far.
Tomorrow at the latest I should have a new video up.
I'll also change the pictures in OP to be less trash and probably rename the topic, be sure to vote on your favorite name.
