WOW, that's old. I can't believe I still have that in there. My advice is to ignore the .txt file -- OpenZone has built-in help that I keep up-to-date.
If you just want to try an OpenZone zone, then what you should do is open tutorial_2.scn and choose Export...Export to .S3D. When asked for the output zone name, enter "ecommons". To use the tutorial_2 file, you'll need its textures, which are available here:
http://sourceforge.net/project/showf...ease_id=276191
Unzip all of the texture .ZIP files into your OpenZone/library/textures folder *before* starting OpenZone.
After you export the file the way I've described above, BACK UP your existing ecommons*.s3d files and overwrite them with the ones that OpenZone generates (they'll be in the OpenZone/zones folder). The tutorial_2 file is a very small zone (much smaller than the real ecommons one) and you might find yourself falling as soon as you zone in. Make sure you have admin rights on your server and move yourself to something like 0, 0, 30 (I think it's the #goto command but don't hold me to that). You don't need to worry about EQInside anymore. That was written before OpenZone could export directly to .S3D (besides, I wrote a replacement program called S3DSpy that's way better, but you don't need it here). To leave the zone you'll have to use the #zone command since you won't have zone points set up at this point.
After you've seen the little zone, the next thing you should do is go through the tutorial. Ignore the .txt file: OpenZone comes with built-in help for everything, including a tutorial that will walk you through the process of building the tutorial_2 file I described above. It's a very simple tutorial and shouldn't take you more than half an hour. Once you go through it you'll know most of the basics.
After that you should take a look at some of the zones I've built to see what's possible with OpenZone. They're available here:
http://sourceforge.net/project/showf...ease_id=333409
I've added a lot to the Veldona zone since then and if I have time today I might upload an update. I've also begun working on an elf city (sort of gfay writ large), but it will be some time before it's ready.
OpenZone can't import .S3D files and this is by design. I don't want anyone using it to cheat on live (such as adding shortcuts, etc.). OpenZone is for creating your own zones and I don't think it would be good for OpenZone or EQEmu if people started using it for malicious uses on live. I'm not accusing you of it but it would incur SOE's wrath and I don't want to take the risk. Someone would use OpenZone for that purpose if I allowed it.
