Trasp Bgroung texture on mesh: Problem!

vvvv beta question

I’m trying to create a texture with transparent background. In order to do this, I’m using the DX9Texture with Format=V8U8
(do someone know what this mean? I just made some try on suggestion from sunep)

But, when applying this texture on some mesh, the transparency works only for a direction of view, not for the opposite. It is supposed to do this? There is some way to let the transparency works in both directions?
