I found that the terrain service normally used on CesiumJs will have problems on CesiumForUnreal, such as a lot of white blocks. (LogPhysicsCore: Error: PHYSX: (D:\Build++Fortnite\Sync\Engine\Source\ThirdParty\PhysX3\PhysX_3.4\Source\PhysXCooking\src\mesh\TriangleMeshBuilder.cpp 802) reported in Unreal4.26 version eINVALID_PARAMETER: TriangleMesh::loadFromDesc: desc.isValid() failed!).
I compared my terrain service with the official terrain service and found the difference in the layer.json file.
"bvhlevels": 6, "description": "", "extensions": [ "bvh", "watermask", "metadata", "octvertexnormals" ],
I want to know if the cause of the build failure is bvh? And how to deal with terrain to be compatible with bvh?
