Hey Dustin. Huge issues with forearm roll bone.

Submitted by: nghia59 nghia59

I just bought the rig a few weeks ago hoping that it would give me an easy win for a personal project at home but it seems like the forearm roll bone is rolling in the wrong direction.  Is there a patch that fixes this or can you have a look at it.  Right now I'm working in Maya 2012 SP2.  Any help would be greatly appreciated.

P.S. if you want to hit me up through email its

    Actually, now that I look at it through hypergraph it seems like the bone orientation might be locked or set at the wrong orientation. :/ - Nghia

    Also as a note, this is my bind pose. It is the optimal way to get realstic deformations without losing proportions so it can't be changed. - nghia

    Just thought i'd add i was using the non-toon arms. The twist works fine with toon arms.

    Hi Dustin I have the exact same problem. I'd love to use the rig for a project but the forearm twist is causing me all sorts of problems. My model is also in a 45 degree arm pose (slightly different than above though) and the forearm twists incorrectly. When I look at the x values in the forearm they seem to be mimicking the x values of the wrist exactly rather than 50%, as one would expect for a forearm twist setup? Not sure how your forearm twist works so maybe it's different... but I've tried twisting the wrist all the way round in the dummy rig , and re-binding and i still have the same problem. It would be great if you could email me with a solution at - perhaps you found a solution for nghia? I'm desperate to get going with it as the rest of the script is great! thanks in advance!

    Hey Bert, Nghia and I have been working on a fix. If you don't mind, could you email me your dummy rig? That way I can test it to make sure the latest version of the rig will resolve that issue. You can send it to dustin(at)rapid rig(dot)com Thanks!

    I should also mention that the forearm joint is supposed to have 100% influence from the wrist twisting. The reason for this is the vertices that are close to the wrist but shouldn't move with the hand should twist more than 50% of the wrist's twist. By having it at 100%, you can then weight these points entirely to the forearm joint. Vertices that are halfway between the elbow and wrist would have 50% of their weight painted to the forearm joint and the other 50% to the elbow. I hope that makes sense. Dustin
