Newbie: Bad Blender mesh - KeyError in writeSkinWeights

[centipede]

I'm a brand new user of Irrlicht and think it's a little wonder. However I'm having problems exporting the following mesh, and I hope somebody could help me out...

http://artcamilla.dk/centipede/vaultage ... _237.blend
..And this is how far the exporter got before it stopped:
http://artcamilla.dk/centipede/vaultage ... s/humans.x

I am using Jox's directxmod exporter v. 1.3.2 and blender 2.37a. This is the error it prints:

Code: Select all

Traceback (most recent call last):
File "<string>", line 1547, in ?
File "<string>", line 1481, in my_callback
File "<string>", line 577, in writeRootBone
File "<string>", line 509, in exportMesh
File "<string>", line 764, in writeSkinWeights
KeyError: 88

There is a mesh and an armature.

Any help would be wildly appreciated!

I didn't look at your blend file, but my guess is, that you left at least one vertex without a bone assignment. Make sure, that each vertex is at least in one vertex group assigned to a bone.

Still got the error even though I have selected all vertices and assigned to the 'torso' vertex group, which would make some of them belonging to two groups. But thanks for the hint

EDIT: One point worth noticing is that I added the bone 'torso' after I had parented the armature to the mesh (because of another script error actually).

GOT IT! There's a little vertex right in between the lips, and a couple of edges attached to it. Adding a few additional print clauses in the script helped me catch it. Sorry for alarming people.
