Moho Animation Forum

I'm trying to follow the beginners course on YouTube. On the left leg, creating a smooth joint for bone pair went fine. I followed exactly the same steps on the right leg and the option is greyed out. Is there something I'm doing wrong or is this a bug?

I tried updating to the newest version of Moho 14 and it hasn't helped.

Smooth Joint should work fine in 14.2. I've used it for a few projects already with no issues.

Things to check:

- Ensure you select only two bones plus the art layer you wish to bind to the bones.
- Make sure you don't have another binding method applied to the layer that may conflict with Smooth Joint; like Bind Layer for example.

If you're not sure about the second point, select the layer and then choose Bone > Reset All Bone Rigging. This will reset the binding for only the selected layer to the default Flex-Binding. Now select the art layer, the two bones, and choose Bone > Create Smooth Joint For Bone Pair.

Hope this helps.

The bones also need to be in a straight enough line.

Your pair of bones is not straight. It has to be straight enough to used smooth join.

The smooth joint option in bone is availble only if:
1- you selected 2 bones and then select the (for example leg) layer. it will not work if youare on bone layer
2- Angle restriction: If we assume that two bones that are in a straight line have an angle of zero between them (of course, in reality it is 180 degrees), this angle between them must be set to something between 0 to 10 (bigger than 0 to less or equal to 10) 10>=angle>0. it will work in both direction( -10>= and 10>=) But NOT zero. I wonder why developers not said about it in Moho help.

@PetrichorCrown,

You may have seen this by now, but for anyone needing more info, I made a tutorial about this topic...



Smooth Joint is Method #3 in the chapter marks.

BTW, I meant to comment earlier: Cool design!
