Warning Missing influence on vert 26520. Weighting it to root.

I keep getting these messages when I import my mesh from Blender.

great warning… what good is it if I don’t know WHICH vertices are 26514 through 26529?

How can I find out which vertices have missing influence? And why would they have missing influence?

It means that some vertices haven’t been weighted to any bones. One way to find out which they are is to open blender, select the armature in pose mode, and start translating a bone that is near the top of the hierarchy (such as the root bone). Any vertices that aren’t weighted should stay in place while the rest move with the skeleton.
