  1. Project Settings -> Engine -> Rendering -> Postprocessing -> set Custom Depth-Stencil Pass to Enabled with Stencil

  2. Add Post Process Volume in Level, Edit properties in Detail Panel -> Post Process Materials -> Array -> Add Asset Reference and set a material of outliner.

  3. Select target mesh in Level Editor, Edit properties in Detail Panel -> Override Materials -> enable Render CustomDepth Pass, and set value of CustomDepth Stencil Value as the material provide.

code:

if (MyMeshComponent)
{
    MyMeshComponent->SetRenderCustomDepth(true);
    MyMeshComponent->SetCustomDepthStencilValue(1);
}
