I'm currently trying to render the ocean in Solaris.
But when I use the ocean surface, motion blur is disabled.
The motion blur works fine with the basic liquid shader, but I still want to use the ocean shader.
Does anyone know why?

I've had tons of problem with solaris and motionblur. Mostly due to abc writing scale and scale affecting the motionblur.
When all else fails, dropping a cache node with 5+- rolling window frames seems to do the trick in my cases at least.
