Vengence, most of the detailing on the Interceptor model so far has been to the engines. I'd post a picture to show you, but for some reason my internal access seems to have been revoked following the forum change.
There was a really early version of this that used the original models (in fact you've already seen them
here) but we decided that it looked pretty crap. Hence, we decided to begin revamping and greebling up the models, and create higher res textures. However, like nearly all projects nowadays, we are sorely lacking in modellers and texturers. If you have skills in either of these areas please feel free to contact Grug and discuss joining the team.
Actually, part of the reason that the mod has stalled is that right now getting the models and textures upgraded is basically the only step that we can really take "forward." Conceptually, we've got a ton of work done. The first half of the campaign is pretty much nailed down overall storywise, with the first couple of missions in various stages of writing by me. (Something which I've been slacking on lately due to homework... :-/ ) Our main characters are all fleshed out, and apart from the odd ship or two, the tech room descriptions are done. (They're impressive too: we've got some very talented writers on the team.)
Don't worry guys, TAP is dedicated to getting this mod out there to the community. We all love Homeworld dearly, and even if it takes us a long time, we're going to bring it to you in a FreeSpace flavor. If nothing else, we promise to have it done by the time Homeworld and FreeSpace 3 are out. ;-)
