Mcreator - Vanilla Mob Model/Animation Location??

by that, do you by chance mean to talk about finding the animation in Minecraft's source code?

if u didn't know yet, Minecraft's deobfuscated source code can be viewed in the project browser at the leftmost part of the window. see a gray line? hover your mouse pointer over there and you can see a two-pointed arrow. drag that arrow to the right and you can see directories of several different libraries/folders included in your workspace. and if i'm not mistaken, expand the "external libraries" directory, open the "Gradle: forge-1.14.4-..." folder, then navigate to net/minecraft/. you can see folders over there containing everything including class files for several components of Minecraft. for the animation code though, idk where it's stored since I still haven't found and seen it yet...

take note, Minecraft's source code CANNOT be modified since it's seemingly write-protected in MCreator. and you really shouldn't do anything that violates Minecraft's terms of use, just saying.
