Transparency nug? How to set this up?

Hey guys,

I’m fighting with an asset I’m trying to work on. When I put this on masked blend mode I’ve got the grid, but not the glass. When I put this on translusent, I’ve got the grid AND the glass, but the other part of the shadder is totally broken. See the image.

In fact I would need something to say, this part exist these not; and in the same time saying this is transparent, this is opaque (the masked mode combined with translucent…)…

The model is one single texturemap (opacity on alpha channel), can’t put a separate object and texture just for the grid and the glass…

It’s driving me crazy, don’t know what to do.

Help please!**

Thanks!

Use two materials with the same texture instead?
