I will take look at your quide.
Tho what I dont understand is that most tell, take a sample before a hole, see if there is any, and then go in, but the samples only work for that chunk you tog the first sample in.
Will say if you take a sample in a chunk, then you go down in a mine, and then go over to a new chunk berceuse you go deep, then your first sample mean nothing, then it is pure luck you find what you are look for?
I use the ".debug wireframe chunk" command to see the chunks I am working in, and I know when I pass the black line, I need to take a new sample, if it is up, down or to the sides.
I have now looked at your guide, I have don a lot of what you type there, but not to the point, I will try, but what if you dont have node search mode. The server I paly on is 100 % standard, and dont have it on.
