I'm just getting into rigging and animation with Blender and I've run into a quite odd-looking issue in a very basic step.
I'm doing a REALLY basic rig: I have a column (a tall cube with about 10 inner segments), which I rigged up with a bone chain, that is a straight line of 10 deforming bones. I used automatic weights and corrected it in weight paint where it was necessary (each bone should move 1 level of the 10 inner segments). However, what I get is that the bones not only move the vertices with weights over zero value (what I'm aiming is 4 vertices per bones), but each and every bone moves the bottom face of the mesh as well. The weight values of all 4 vertices of this bottom face is actually zero (or very close to it), in all vertex groups. At the same time 1-2 of its vertices act like they had about 0,75-0,9 weight values, when I rotate any bone, in Pose mode.
When googling it, I didn't even find similar issues, I'm quite paused what they problem may be. Has anyone met perhaps similar situation before? Thank you if you can help in any way
