really ugly ms3d model bug, and getXJointNode

luvcraft · Post by **luvcraft** » Sat May 15, 2004 11:02 pm

So, I have a mesh that I made in Milkshape, and when I export it to an X file and load it with Irrlicht, it looks fine, like this:

however, if I load the ms3d model that it's exported from, it looks like this:

Originally, I was just ignoring it and only using the X model, but now I really need getMS3DJointNode, and since there's no alternative for X, I'm stuck using an ms3d model, but the ms3d model doesn't work. The alternative is to download the 180+ mb dx9 sdk, and recompile Irrlicht with a getXJointNode function, which I'm in the process of doing right now, but it's kind of a slow download.

Does anyone either:
a: have any idea how I can fix my ms3d so it displays properly in Irrlicht (I have a feeling it has something to do with the fact that the model has a "cel outline shell" around it, with inward-pointing normals)
or
b: have a version of the Irrlicht library compiled with a getXJointNode function that they can send me?

It's especially frustrating since getMS3DJointNode would work just fine for an X file too, except for the fact that it checks first to make sure the mesh is an MS3D.

Thanks in advance!

I saw that exact problem.

It had to do with keyframes created by MS3D. I had my friend look at my model and he added the frame properly and it worked. Wish I remembered more about what he did.

in the thread that you linked to, did you end up using an ms3d or an X? It looks like an X from your code snippet.

Well... I loaded the MS3D and just recast it as an X, to be able to use getJointNumber

Couldn't you just use the getJointNumber() for MS3D?

I've been trying to get it to work with my X model, but for some reason getting the transformation of the joint only returns its rotation relative to its relaxed position, and doesn't return translation at all, which is pretty useless.

Am I doing something wrong, or is it a problem with the engine?

Aha! I finally figured out the attaching nodes to joints problem; I had initialized the weapon using a home-made class that automatically assigns collision detection, which, oddly, didn't affect it, but did prevent it from being moved by anything else.
