No, some trees aren't recognized by the harvester, and you would be able to add it to the harvester's "this is a tree" list with some minetweaker code like this:
I don't know the ID codes for Redwood logs or leaves, so I just put a guessCode:import mods.mfr.Harvester; Harvester.addHarvestable(Whatever the redwood log is known as | <natura:redwoodLog>?,"tree"); Harvester.addHarvestable(Whatever the redwood leaves are known as | <natura:leave:5>?, "treeLeaf");
just went into a test world to try out and the harvester recognizes the redwood tree right away
I tried harvesting the tree, but the harvester didn't really work at the bottom, but as soon as I moved it up 1 ring it immediatly started harvesting
all was fine till it hit the leaves, because there's so many leaves it takes ages for the harvester to harvest them all
so it works, but very slowly, and it ofcourse causes alot of lagg...
