Techne model not working

Hi, I made a ustom mob model using Techne.

It works when importing it with Techne or Novaskin.

However, I made a mob using that model in my mod and it had missing texture.

Here you can find the model and the texture:

I have already made a few models using Techne and they worked. I had an issue with mirror textures in my previous models, but this time there are no mirror textures.
