The plugin isn't actually required to
make the models; it's only needed to get models into the game.
What I'm saying is, you could create a model in Maya 2013 and then send the files to me (or another modeller with Maya 5.0) to export them to GM format. The finished ship would then be made available to everyone and probably added to the next Build Mod update. This way, you can focus on the modelling part, and leave the tricky export process to someone else.
That is, unless you're
really keen to learn how to do the whole process yourself, which requires a lot of work on my part to explain it all to you... and I'm quite busy at the moment.
Armada, can we upload that plugin on a DropBox account somewhere?
It doesn't matter if you're a Moderator on here or not; the problem is that the FTP is down.
Also, the plugin only works on Maya 5, I think. I'd be well surprised if you could get it to work on Maya 2013.
I tried the plugin with Maya 2012 on my old PC, and as expected, it didn't work. Apparently, this goes for most Maya plugins; they only work for the version of Maya they were made for.
It might be possible to get it to work with the help of a programmer, though.
As for uploading the plugin: I suspect everyone who needs that plugin also needs Maya 5.0, so they both need to be uploaded to one place.
I don't know where would be suitable to upload them, though. I have SkyDrive and Google Drive accounts I could use, I guess.
