Problem with transparent textures

[maru]

Here is my problem, maybe someone will help me:

I am trying to make a scene where one object is made of transparent film with printed text on it. You can see it in the attached images.

I made two maps: one for diffuse colour and one for refraction/opacity.

After rendering, all the letters have dark outlines, which is obvious because of antialiasing (re1.jpg). Dark edges of the letters are semi-transparent because of antialiasing in opacity map.

So I tried a different method (re2.jpg) but then the masking shapes are visible because I don't want the film to be completely transparent and diffuse colour is visible.

I also tried saving diffuse map in .png format with alpha channel but max (or Corona?) thinks alpha is white and the effect is still not good (re3.jpg).

I want the film to be opaque where there are letters and shapes and transparent (black with 80% transparency) in the background. And I don't want those dark outlines. I'm lost. How would you do this?

Looks like the only way to do this is by disabling antialiasing when saving these bitmaps.

Hi maru,
perhaps this example can be useful to you

Did you try by changing the bitmap filtering inside 3ds max?

[maru]

Yes, but it's not that kind of problem.

Maybe Rafpug is right it can be achieved with some blending magic.
