Iray Ocean Scenes is a collection of both underwater, and above water sea-based HDRI environments. The environments use various reflectors and VDB volumes to better merge your characters/props into each scene, but the HDRI domes can be used independently. Each scene has cameras place at various angles which would cover a large ship for the above water HDRIs, but you can easily move the camera to accommodate smaller boats. The underwater scenes contain cameras at suitable angles for a diver or marine animal, but again, you can shift the cameras around to accommodate a different subject. There is also some bonus shark VDB blood, created for one of the promotional images. Each HDRI is exported from blender at 8k, and 32-bit depth.
