Yes, there was no alpha at all. Fixed by: 1. Applied Arnold geometry properties , and unchecking Opaque (checked by default on all geo when using Arnold) With that, "Opacity" parameter on a Standard shader can be used to drive the opacity on the entire geometry
2. Played with the transparency with the Refractive = 1 and set the IOR as desired. 3. Finally I could do a render on .exr with "RGBA" option enabled (I missed it on .PNG because it´s not float) Then I got clean and crisp alpha as desired with Transparent objects (refractive issue) with no probs at all.
