Alpha chanel doesn't work for Spectre

Reza

I'm working on this Specter weapon which has a lot of smooth curves and I couldn't figure out how to fit all those smooth edges in 300 tris, so I decided to use custom alpha in some parts, but apparently almighty specter doesn't support alpha channels (no only for weapon but for all the slots).
Just to make sure that I'm not doing anything wrong, I uploaded the same files for legion commander and the alpha is working there.
So what should I do now?
I don't know any proper channel to tell volvo about this and that dota developrs forum is no help (from my past experiences).
Here u see the color map with crazy alpha and how it works for spectre and legion:

I'm sorry to tell you but some Characters simply do not support an opacity channel...

u can compile your item manually and add some words about alpha in file (forget file format)but it is very problematic. i make that when compile shenmi-enigma (for wings and mane alphas)

hell yeah!

Now what about submission?! how can I submit it when I manually compile it?
I should just submit it the way it is and hope that volve will compile it correctly? or I should mention in in "developer comments" section?
