Need help with a model

[Jaccouille]

Hey guys, I am working on a model, I got a small issue which I don't understand, basically I imported the goblin laboratory to use the big scope thing, the glass part of the scope change texture during animation, I kinda want it to use it's base texture so it look like more like glass.

Here's what I want :

Any idea why? There's still stuff I don't know about modelling.

Should it be like this?
I "fixed" it by removing the blend filter mode from the glass geoset's material.

Yes, exactly what I wanted, blend filter it was, dunno why it was like this in the goblin laboratory model, I see there's an animation on this glass texture, I removed it, thank you.
