Hello there

This is my first time modding, and the first time with blender. Sorry if it's a silly mistake.

So I wanted to make a mask mod. I got my mask model online (which was for SFM). I then converted it to work with blender. I then followed a video on YouTube on exporting a mask to PAYDAY. I followed the steps. I fired the game up to see the results, but nothing was changed.

I checked "mods" in the options, and my mod is there. I checked the files it replaces, and they look like what they are.

5 hours passed and no solution was found, I redid the mod twice, but even after all, the mod still doesn't change the mask.

I'd appreciate if anyone could find the problem.
