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?
