The licensee reports that this issue is caused by the following code not performing a Buffer update.
.\Engine\Source\Runtime\Renderer\Private\ShaderBaseClasses.cpp
void FMeshMaterialShaderElementData::InitializeMeshMaterialData(...)

Therefore, the following fixes may solve the problem.
if (SceneView /* && StaticMeshId >= 0 */) { checkSlow(SceneView->bIsViewInfo); const FViewInfo* ViewInfo = (FViewInfo*)SceneView; if (/* Add */ StaticMeshId >= 0 && MeshBatch.bDitheredLODTransition && !(bAllowStencilDither && ViewInfo->bAllowStencilDither)) { if (ViewInfo->StaticMeshFadeOutDitheredLODMap[StaticMeshId]) { DitherUniformBuffer = ViewInfo->DitherFadeOutUniformBuffer; } else if (ViewInfo->StaticMeshFadeInDitheredLODMap[StaticMeshId]) { DitherUniformBuffer = ViewInfo->DitherFadeInUniformBuffer; } }
1. Use DistanceCullFade node as the material.

2. Set the Material and Desired Max Draw Distance for each mesh.

3. When played, it works on Static Mesh, but not on Skeletal Mesh.
