Thanks for posting this here.
Yes, there's a version difference but not much has changed in functionality. A lot of code has changed, new ports added for other applications. Little has changed for the softimage ice node though.
The compiled version can be downloaded fromhttps://bitbucket.org/amaanakram/aaocean/downloads
The shaders have changed though.
-Normals shader does not exist anymore. It doesn't work well within the context of layered oceans. And Arnold generates normals quite nicely with auto-bump
-aaOceanData shader for mental ray and arnold. It outputs vector displacement as RGB and foam info in the Alpha channel. This sets up the foam to be in sync with the ocean surface, and conserves memory, evaluates faster. You'll have to use it in conjunction with the Vector Displacement shader from mental images that ships with XSI
I don't plan to make more changes. I may added a physically-based sea shader at some point, but not much else. If you have any suggestions, please do let me know.
