Disappearing model with skin applied.

Hello,

I've searched the forums and come up with nothing so if it has been brought up but I didn't find it, forgive me.

All of the sudden when I put a skin modifier on an object it disappears from the oFusion viewport. as soon as I delete the skin modifier [if max doesn't crash] the object appears again.

I have reset xform and done everything that I could think that would be causing the problem. So as a test I created 2 tea pots, started the oFusion viewport and the 2 tea pots appear. Then I put 1 skin modifier on one of the tea pots and it disappears. The selection box doesn't even show up around it if I select it in another view port.

This is brand new and I've exported 2 animated models so far with no problems. Any ideas?

Also, when trying to export I get a whole bunch of errors:


I'm guessing it gives me 21 of these errors one for every bone:

Caught exception in GetSkinVertexData()
Please report it

and then finishes with this.

Caught exception in CreatePhysiqueBoneList()
Please report it
Compiled 21 skinbones to model
Object has 1 texture sets
Compiling material 02_-_Default
New texture unit RobofistCompleteMap.tga
Caught exception in compilemesh()
Please report it

All your vertices should be assigned by at least to a bone, if not bones are assigned to the vertex (with an usable value, higher than 0.01) the mesh will not be displayed (or the parts that dont have vertices assigend)

If you simply apply the skin modifier, without assigning bones, it wont be displayed, as the skinning system wont be able to derive the vertices positions from the bone matrices

Test with a simple object, add the skin modifier, add two bones and assign the vertices with full (1.0) weight to the bones, activate display weight influence, update the oFusion viewport and you will see the object with the weight colors

I guess that was it though I couldn't find the vertices that weren't effected by any bones so I just went ahead and redid the whole skeleton and took this into account from the beginning.

Thank you.
