I have a animation problem when I rotate the bones they rotate and scale the mesh. i dont want it to scale. I was wounder if anyone knows how to fix this problem?
What do you mean they scale the mesh? You actually see the mesh getting smaller? Do you see the bone getting smaller also? How are you rotating the bone? RKEY?
Sorry for all the question, just trying to get a handle on your problem.
Try looking at the ipo curve editor to see if the size is of the armature is changing. Do you have a blend file to demonstrate the problem?
I upload some pictures and I move the bones in pose mode using the rotate handles


this is how it starts


and this is what happens I have tird resetting the program but it still has the same problem. Do you need more infomation?
dont you have the option of parenting that bone to those vertices?
you can weight them
i think there might be an example in the blender manual for the gingerbreadman
or the second edition of blender magazine in rigging the spider
