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: http://www.mediafire.com/folder/2r2dh3r2li7vh/Ice_Boss
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.
Here you can find more info:

EDIT: it seems that the bug reappeared in 1.8.0
I have imported your model and texture in MCreator 1.8.0 so it seems that this bug will be resolved in MCreator 1.8.0.
