Another Ocean / Bake/ render farm question

I have found the best 'large open ocean for blender.

by Dylan Neill.

So i did this ocean and its beautiful. Now i have a client that needs an ocean shot.
ive baked two Sep Ocean modifiers as displace >
the two folders are labelled ocean a & b respectively.

mixing them by black and white noise texture to reduce tiling.

heres the problem.

when i upload my scene to a render farm my Mesh plane comes out flat and shiny.

how do i tell blender to make these relative paths. even though ive clicked it and did make relative etc, but where do i put the // ?

i figured it out using Render st.
making that folder setup with reference locations within the same folder. a relative path.

How would one go about adding the wake effect and waves / ripples / on this displacement based Ocean which is a beauty in any even but still not a mesh .
was possible to bake this? some how?
