UE 5.8 compatibility release
Oceanology Legacy 5.8.1 — engine compatibility for Unreal Engine 5.8. No new features; the next feature release is Lite 6.0.0.
Oceanology Legacy 5.8.1 is a compatibility release and nothing more. It builds and runs the existing Legacy plugin on Unreal Engine 5.8. There are no new features, no new actors or components, no parameter changes and no rendering changes.
Why it exists
Lite 6.0.0 is a rebuild on a different codebase, and a rebuild takes as long as it takes. Projects do not wait for it. If your production needs to be on UE 5.8 now, 5.8.1 gets your current Legacy setup onto 5.8 without touching your scene, your presets or your blueprints. When Lite 6.0.0 arrives you migrate on your own schedule instead of being blocked on an engine version in the meantime.
What is in it
- The same 17,478 lines of C++ across 107 files, two modules and four shader files as the release before it.
- Engine API updates so that code compiles and runs against UE 5.8.
- No new systems, no new classes, no changed defaults.
- Existing presets, materials, blueprints and level setups keep working as they are.
What it is not
It is not a preview of Lite, and nothing in it comes from the Lite work. Lite 6.0.0 is the Pro codebase with different actors, different components and a different authoring model, so moving from Legacy to Lite is a real migration rather than an in-place upgrade. Treat 5.8.1 as the bridge that keeps a shipping project moving, and plan the migration to Lite 6.0.0 separately.
