I didn't make it!
i've download a lot of yoda model whatever in jk2 or 3, but they always not in the right size, i always get a giant yoda, bid head big body, hahaha, so what should i do to solve this problem thz:beer:
For MP player models, you can use a mod which supports the modelscale feature.
For SP NPCs, you can set the model's scaling in the .npc file. I believe Yoda's scale ratio is about 75%.
I don't know how, and I don't know why, but this is totally Sheep's fault.
