[Need help] Md3.cfg problem

[Cleaner]

Resurrected topic for good reason.

Here comes what I'm struggling with...

I am sorting a few decals mapmodels to add as "décor", simple stuff like a single plane with only 2 triangles but I'm struggling with transparencies.
A picture speaks louder than words so here you go...



1 is the png image file (all but black parts is transparent)

2 is what I was expecting as render (as it looks like in my 3D window)

3 is what actually comes up ingame

I have tried all sorts (dozens) of settings in Milkshake and within the model's cfg like mdlalphatest aso aso (even tried Sauer commands but they are incompatible with our engine) but I can't get a true pixels rendering... Any idea?

EDIT: Event the tags, unless dark grey they come up too flashy :(
