Minecraft wiki entry for Creating_Forge_mods, associated text: The best way to model mobs is probably blockbench (blockbench website). Blockbench is a free modeling tool, and it would be much faster and easier than taking the other approach, which is slow. If you want to model with it, simply make a cube, position it, rotate it, size it, and make your model the way you want to make it. If you need more cubes, you can easily make a new one. This is probably the best method for this. It is fast, easy, and customizable.
