Multiple Skins for mobs

[xWildSlicerx]

I am trying to activate the random skin selector for mob skins but I'm not quite sure how to do it through Feed the Beast.

I have roughly 20 creeper skins, a dozen zombie skins and a dozen skeleton skins but only the first one is being selected.

Can someone help by pointing me in the right direction please?

You need Optifine, but it can be a bit buggy with some other mods in FTB; particularly MPS

Yep Optifine. You will find the setting under Options->Video settings->Quality->Random mobs
