Missing Reflection Information?

I have a weapon on my server, when i use it, the texture and the model of the weapon are totally fine, but the reflection overlay of the weapon is pink checkerboard texture. Looks very annoying, a normal weapon texture with a transparent missing texture overlay. I tried using $phong instead of cubemaps but it had no effect on the issue. Do i miss something in the vmt, or what could cause that?

I could supply screenshots if needed

EDIT : Nevermind i tihnk i fixed it. i tried using no shader at all, no phong, no cubemap info, nothing. and now it works fine
