That fixed it thank you. I changed the export line of the config file to -proj [elevation 90]. Fairly obvious when you look at it.

All the (relevant) elevation scraps, maps and exports will need to have -projection [elevation 90] as part of their definition. (If you just specify "-projection elevation" then Therion will default to an elevation looking 0 deg, or north for that object) Many versions back I discovered that the direction must be specified exactly the same way in each scrap, map and export definition, I presume it is still the case. ie -projection [elevation 90] is not recognised by Therion as the same as -projection [elevation 090], and so this can be a reason why some scraps or maps are dropped from an export.
