Quake3World

Hi all, first post here. I'm rather desperate now because I need to export a minigun model I made for Jedi Academy:

As you can see, the UVmap/texturing is done for it too. However, it was created in Lightwave, which is at a disadvantage when it comes to exporting models for Q3-engine games (the only MD3 exporter is no longer supported by later versions of Lightwave)

Anyway, I've got a few questions, hope you all can take some time to help me out

1) How are tags made? I understand that tags are right angled tris, with each vert defining the angle that the object is facing. However, I also read that tags are used to join objects together. If you look at my minigun, it definitely has more than 1000 verts, which isn't supported in JA (Jedi Academy), so I'm splitting them up into 3 different meshes (handle, main body and barrel). In this case, do I have to create separate tags for each mesh? I've also read that tags should be linked to bones, but my weapon doesnt have a bone! Then there's also the issue of assigning a function to each tag. In JA, there are tags that say tag_flash, which are used as placeholders for the muzzle flash. How do I assign a function to the tag, or even find out what the tag really does for that matter?

lol I'm sorry this is all too much for me, and I apologise if I sound like I'm going to throw a hundred questions at one go

2) Is it possible to script a rotating barrel that accelerates/decelerates for MD3?

As you can see, my main query involves around tags. I want to get to the bottom of this issue. Find out what on earth they're for, how I can manipulate them and create them

As far as assigning functions, you just name the piece of geometry whatever tag you want it to be (tag_flash, etc.). I'm pretty sure that the rotating barrel business would need to be a cgame code change... Getting around the 1000 vert limit only means that a single piece of geometry within your mesh can't have 1000 verts, so you can just detach your handle and barrel from the main body but still export them all in one .md3. This generally leads to tiny cracks between the separations because the verts are no longer welded (or something, i'm talking out of my ass), so maybe there's a better way to do this. I'm not sure about the bone issue.

Hope that helps some! What res is the skin by the by?

Hi Kaz, yup that helped a lot. I have more questions though, but I'm in a rush now. I'll post em later, as I know another kind soul will help me

The skin's 512x512

More questions

- How do I attach the tag to my model?
- About the assigning functions thing, what I meant was, instead of tag_flash, let's say I want to create a new tag of my own eg. tag_crazyhugegiraffe. Do I define this in the code?

Yep. Without the corresponding cgame code, your custom tag won't do anything.

Probably not, VQ3 already supports tag_barrel.
