Getting started

To add a planetary ocean to your level, follow these steps:

1. Add BP_PlanetaryOcean to your level Drag and drop the BP_PlanetaryOcean actor into your level. This actor controls the ocean’s quad tree and mesh generation settings, such as resolution, radius, and LOD (Level of Detail).

2. If you don’t see the ocean — you’re inside it. Since backface culling is enabled by default, there’s no visible geometry either. Disable Nodes Backface Culling in a Quadtree section of BP_PlanetaryOcean and press F to focus on the ocean sphere. You can then re-enable backface culling.

3. Configure the ocean’s settings In BP_PlanetaryOcean, adjust the ocean’s mesh settings (radius, resolution, etc.) and quadtree settings to fit your needs. Hover over variables to see detailed explanations of what they do. Switch to wireframe mode to better understand how mesh generation behaves.

Explore the Ocean Parameters section of the BP that controls waves generation.

1. Additional notes Ocean material surface settings are defined in the MI_PlanetOcean material instance.
