- get Minecraft [tlauncher](https://tlauncher.org/en/) [linux](https://rutracker.org/forum/viewtopic.php?t=4891689) you need java installed start it up in creative and spawn the mob you want by pressing T and pasting this command /summon pig ~ ~ ~ {NoAI:1} [usefull minecraft commands](https://github.com/22i/minecraft-voxel-blender-models/blob/master/usefull%20minecraft%20commands)
when exporting mobs that hold items like: zombie pigman. baby zombie pigman, vex, skeleton, stray, wither skeleton, illusioner and vindicator you have a choice between minecraft default item or pixel perfection item. If you want pp then delete the other holdable item without pp in the name.
if something is off, some cube is in wrong location or if animation is broken like with wither, enderdragon, wolf and skeleton reopen that .blend skip origin to 3D cursor part and put model into middle manualy.
