Hi,
I am using UE5.8 preview, and am having some trouble implementing some water bodies with MeshTerrain.
Replicate:
- Duplicate MPD_Default to MPD_World and create a water layer.
- Create Plane then scale it up. Go to Mesh Terrain Mode. Select Plane and click convert so you convert the plane to a Mesh Terrain Object, set the definition to MPD_World.
- Select MeshPartition (object created in previous step) add MeshPartition component.
- Create WaterBodyRiver actor and place on terrain.
- Add RiverModifier component to WaterBodyRiver actor.
- Set AffectedMeshPartition to the mesh partition created in step 2. Set PriorityLayer to the water layer created in step 1.
- Nothing happens.
I have attempted this entire process agaub but instead of converting an existing mesh, i create a MeshTerrain from scratch using the “Create Rectangle” button. Then I add the river in the same way, and this does seem to create a river correctly. I attached two images in case it helps.
Does anybody know if I am doing something wrong or is this something that will be patched soon?
