How to Import Mini-Kits?

[Chuny]

Hey everybody!
This is, probably, the stupidest question but I can't seem to find how to import mini kits into the game.

I've tried with CM12 but when I click the minikit image file (in png file format) it, I get an error message:

Error: 5026
Cannot find the template .big file

And I haven't been able to find any other tool nor tutorial around the web to do this. I hope you can help me.

Thanks in advance.

Try using RX3 Master or Texture Editor

Thanks. Where can I download RX3 Master? I can only find File Master.
