but the final result is translucent:

i used the Leveldesign_Workflow level from the content Examples.

I’m also interested in this.

Have you tried to enable DBuffer Decals on your project? It’s on Project Settings → Rendering → Lighting → DBuffer Decals. You will have to restart the editor and change decal blend mode on the material to DBuffer something.

Hope it helps
