Need Help With Blender Rigs

So I'm using Rymdnisse's Minecraft Blender rig, and I imported the slime model. However, for some reason, transparency is derpy.
In the editor, the slime looks like this:

But when I actually render it, it looks like this:

Any help would be greatly appreciated. Thanks!

 

I know nothing about this, but I'm pretty sure it has to do with your render or transparency settings, not the rig itself.

 

I have a feeling that you're right and some setting somewhere is wrong, but I don't know which one.

 

Try changing blender render to cycles render. YOU can see the selection at the top of the screen

 

Alright, I'll try that.

 

Did it work?

 

Nope. I have a feeling it's something with my settings, since when I render it in the source file it works fine but when I import it it's broken.
