I have been experimenting with the Converter program and it seems to work well in creating mdl files which display properly in FSX. They do not display at all in FS9 - I was under the impression (perhaps mistakenly) that they could be used in FS9. Am I missing a step perhaps? I am taking the resulting mdl files and using the Library Creator which came with the Instant Scenery program to create a library of objects which can be placed using the IS program. That works well so far. The Library Creator which I have that came with EZ does not work with these converted files however. Perhaps because EZ works in FS9 only. I am hoping there is a way to use the converted API to MDL files in FS9. Thanks in advance for any suggestions.
