Knee And Arms Won't Bend

[skitz55]

I've and modelled my Character out of polygons use just one shape and sculpted him, everything is fine and looks good.I also Rigged my Character using James Bakins Awesome Rigomatic tool that works very well.The rig doesn't have FK/IK Switching and I made it so it does not stretch when i was rigging it with rigomatic. The problem i'm having is that when i bend the legs using the controls, the legs just sqaush down and don't bend as if there is no Knee.Even though i can see the Skeleton's leg bending.This also applys to the Arms.The Skin is binded onto the rig fine. I feel like an idiot asking this question because it seems simple enough and i have never had this problem before but i jsut can't find the problem so if anyone can help i'd much appreciate it.

I haven't ever used that particular rigging tool. But I've had similar problems, so I think I know what might be going on.

Most rigs consist of multiple sets of skeletons. One is the master skeleton that the geometry is skinned to. Then there are separate control skeletons for things like IK/FK and squash/stretch. The switches make it so that the master skeleton goes back and forth between being constrained to different control skeletons.

My best guess is that your geometry is skinned to the wrong bones in the leg. Even if you don't have FK/IK switching or Squash/Stretch turned on, the Rigomatic probably still created those bones. You must have accidentally bound your legs to the control bones instead of the master bones. If you see the skeleton's legs bending, and the mesh is doing something else, that's almost a sure bet.

Hope this helps. Let me know how it goes

I moddeled the Character and then build a skeleton around it and then used the Rigomatic tool to rig it, i still need to bind the model to the skeleton but i think i may be doing this wrong. I've been binding it to the Skeleton I built. Is that wrong because i can't think of anything else.

Also i havn't changed the skin clusters weights, they are defaulted to 3 is this also a problem that could be causing this?

Does rigomatic automatically generate any bones when you create it? Most rigging scripts do.

If it does, then it's still possible that you've accidentally bound you character to them. You can find out for sure by selecting your mesh, going to the Animation Shelf, and selecting the Paint Skin Weights Tool. Pull up the Tool Settings bar and you should see a list of all the joints that your mesh is skinned to. If there are any on there that you don't recognize, then you've found your culprit.

If that doesn't solve the problem, there's a tutorial on youtube for Rigomatic that shows step by step how to use it:

This is the problem i've been having, as you can see the Leg stretches but do not bend like a Knee should, you can also see the skeleton is doing it fine.

I've been connecting "Skitz" ( Which is the model) to "Skitzskeleton" which i'm guessing is wrong. Also the skin deforms but i guess i edit that with Skin weights.
