Thank you, painkiller, I do appreciate that you want to help. I also thank the others.
No way I'll use bloat code for positioning static meshes especially because I want pixel precision and let's put aside shadow map generation or visual artifacts.
Superku suggested a more convenient solution: edit the object origin in MED and place it where I want an alignment in WED. Of course this is far from neat or what I thought of, but when you only got lemons, what can you do?
