Exporting JEM files into Optifine

[Zak_M]

I have had cubik studio a while know and it's great! one of the best modeling softwares I know, but recently I have had some troubles, when exporting my entity model I noticed that there wasn't a .jem extension instead there was a .jpm Extention, I was wondering if anyone could tell me how to maybe fix my entity. Jem, it's an enderman model btw.

I file path

RecourcePack> Assets >Minecraft >optifine> cem> Enderman.jem

Any help would be greatly appreciated
