This evening I was working on a bug in the NL2000 scenery, the lighthouses did not have a light at night. It seemed that during the conversion to the FSX MDL format the attached effect was lost. Since adding I am too lazy to add all those effects by hand again, I added two new features to ModelConverterX.

You can now duplicate an attachpoint in the attached object editor. This can be useful if you need one attachpoint for day and night and another for dusk and dawn. In the effect parameter editor I have also added two more buttons to add the presets for day/night and dusk/dawn parameters.
