Hi there,
I tried out the fast caustics solver and i love the results.
Unfortunately, due to my incompetency, I don't get why they are not visible in my Photoshop file ( see attached image ).
I saved the file as a 16bit PNG with Alpha Channel
When i save it out as an EXR, the caustics are visible, but there is no Alpha channel.
I also tried "caustics only in caustics pass" but i didn't see further options when saving the file, nor a "caustics only" pass in the picture viewer
Thanks!
Andrej
