After writing a simple maxscript for exporting physics data into physx, and working for hours with the .x format trying to get animations and meshes together (at the same time!) I decided the format itself was just too complicated and not even worth debugging so I came up with this
Code: Select all
<mesh numverts="3" numtris="1" material="material.material">
x y z
x y z
x y z
0 1 2
</mesh>
<bone name="parent" position="x,y,z" rotation="w,x,y,z">
<bone name="child" position="x,y,z" rotation="w,x,y,z">
</bone>
</bone>
<skinweights bone="bone name" numweights="1">
vertexnumber weight
</skinweights>
<animation name="animation">
<joint name="joint name" numkeys="1">
time w x y z//quaternion
</joint>
</animation>you might notice the vertices dont even have uvs, normals or anything, but that can easily be added, with a flag for vertex type(its just not my top priority right now)
currently the material loading is not working either(see my thread in advanced help)
if anyone is interested in using it I could post the irrlicht meshloader
but its still a work in progress(every thing but animations works)
heres the maxscript code that generates the text(into the maxscript listener) which I paste into files (.mesh,.skeleton,.animation no .material yet) I could easily write a function to save all to file but anyways
Code: Select all

(Hell I might if I feel up to it.)
or something.
might not be a bad idea.
