I tried to look at them, but the images aren't clear enough for me to make out.  I run at 1680x105 resolution so images can be hard to read at 800x500.  I see what areas you have put arrows in so I will try and figure it out.  I have never had to use this tool before.  Most of my models are scifi and very few terrain.  Thanks for the help anyway.  Could you tell me the difference between using the surface replicator and a regular replicator object?
