I have always been interested in how to blockmix but after a few hours in TMNF of working out how to use ChallengeEdit i gave up.. Can't wait to try this out.
If its still worth mentioning, the way challenge edit works i believe from experience using it is you need to have it running in the background before loading a map to get the correct block order (maybe it was the version i had?). Otherwise you could be wasting time looking for the block you want
ie;
Place the block you want to merge with (usually you would set the block legitimately around the block where you want to merge with in the track editor) where it’s allowed. In this example i'll use above. Save track then count how many places down to the point where you want to merge by using the scroll. Load the map in challenge edit. The last block you placed will be at the bottom of the list.
Fix the XYZ axis (forget which one is up/down) to lower/move the block by how many places you counted. click "save block modifications to memory" before saving track.
