Are you attempting to make a cubic brick?Or a special one, like a ramp.cubic brick ex. = 2x2 brick.special brick ex. = 2x2 round brick.
I'm actually making a grill plate, but I am asking how would you make a .blb file.
Just make it as a .txt, .rtf, or any kind of TEXT file then change the things at last to .blb then package it with a server.cs and description.txt
Like when you "save as" you type .blb at the end? I tried that. Also do you put in the .dts model and collision mesh as well? I am asking this because I saw files with only .blbs and descriptions and pictures.
I believe if you don't want a custom collision, you don't need a .dts model.with a grill plate, I would believe you wouldn't, considering the blockhead isn't going to fit through those holes.
