How to move vertices upwards while bone rotates I've been working on this low-poly mouse character to learn Blender again, but I've run into a problem with my legs that I don't think I know how to fix:

As can be seen, the bottom of the jorts leg clips into the top of the jorts.
I've thought of solving this problem by assigning the jorts to the leg bones, but that moves the belt area backward through the stomach. It was at this point that I realized what I really needed was for the jorts to move upwards as the legs rotated in that direction.
What I'm wondering is, is there a way to, for example, create a bone that moves upwards if a parent bone rotates within a certain range?
I suppose it wouldn't have hurt to just search around the tools a bit more. I discovered that the Transform tool works best for this. I created two bones for those areas near the legs and then mapped a certain rotation range of the thighs to the increase in Z I wanted the bones to have. Just remember that you want to set the Owner to &quot;Local with Parent&quot; if you ever plan on moving your object around, and do something similar with Target (for me I set that to Local Space).
