The one's I'm dealing with are more than Material, they hold
textures, shaders, that's Appearance.<br>
<br>
There is one set of vertices, but each sub-mesh is defined by a list
of indices (each 3 is a triangle) into that one vertex list.<br>

type="cite">Maybe I'm confused, but the point of submesh materials
is that there is only one set of coordinates and indices, but
there are multiple materials. So it's more like you need just a
new kind of Material node, MultiMaterial, that has a set of
materials, and the lists of indices for each material. Something
like<br>
<br>
MultiMaterial : X3DMaterialNode<br>
{<br>
MFNode material [ ] [X3DMaterialNode]<br>
MFNode materialMap [ ] [MaterialMap] <br>
}<br>
<br>
MaterialMap {<br>
SFInt32 materialIndex 0 [0..65535]<br>
MFInt32 faceIndex [ ] [0..65535]<br>
}<br>
<br>
materialIndex identifies which material from the containing
MultiMaterial node;<br>
faceIndex is a list of indices into the one mesh defined by the
containing Shape node's geometry<br>

I've only been dealing with triangle lists, so I'm not sure
how this would scale to other types, but what I was thinking
was something like:<br>
<br>
MultiShape<br>
InOutMFNode appearances[]<br>
geometry MultiITS<br>
InOut MFVec3f coords<br>
InOut MFNode indices<br>
where each of these nodes contains the triangle list,
first index list corresponds to first Appearance and so on<br>
<br>
Problems:<br>
X3D not putting indices in nodes but in attributes<br>
XML is supposed to be order-independent<br>
I'll noodle on it some more<br>

straightforward and somewhat human readable.<br>

Yes, Please. Most importantly how this works with
H-Anim2 deformable skin liveness, which is most needed.<br>

InOut MFInt32 appearanceCount []<br>
