Hi people,
I've been trying to figure out how to use the Fluid Interior node with both the GuidedOceanLayer and the OceanFlatTank. My problem is with using the Fluid_Extended node for the ocean/FLIP object and turning on the Interior node to give me the depth of the ocean.
As the FLIP sim is GEO, merging in the mesh for the Fluid Interior to use, works fine… but as the ocean is Spectra and displaced at render time, the Fluid_Interior just gives a flat surface and I get pockets of interior ‘fog/smoke’ above the waterline.
It seems that the Interior's Material is looking for a Displacement MAP, not a Spectra file, like the Ocean material. So, I'm stumped as to how I use the Fluid Interior with the Fluid Extended, so that it renders both the Mesh AND the Spectra Displacement.
If I shouldn't be using the Fluid Interior at all, in the first place, what should I be using?

Thanks.

Never mind. Resolved.
It seems that the Ocean shelf tool creates a Uniform Volume Material for the _Fluid object, that doesn't work with the Ocean… which requires an Ocean Volume Material, instead.
Obviously, I didn't know about this other material, but it does seem a little strange why the Guided Ocean Layer doesn't create a Material, by default, to deal with the ‘_extended_’ geometry as well as the Flat Tank element, too.
