Moho Forum

I'm trying to animate arms and legs in Moho 12 Pro.
When I select the bones, choose the layer and then select flexi-bind it indicates that the bones are selected.
When I try to manipulate the bones everything that is bind in the normal way (bind layer button) works, but the arms and legs won't work.
I have a group within a group because I'm using a mask. Could that be the problem?

I can think of a number of things.

The most obvious is to make sure the bones have a strength value greater than 0. When the Strength of a bone is set to 0, it won't move anything using Flexi-binding. (Note: Bind Layer and Bind Points don't require bone strength.)

If Bone Strength looks okay, check that you aren't using Bind Layer in a parent group. The Bind Layer tool is for rigidly binding a layer to a single bone, and when this layer is a group, that includes its child layers.

If that isn't it, the layers have probably been released from binding, so nothing affects them. At this point, it's easier to just reset the layer binding. Select the layers in question and choose Reset All Bone Rigging command. This command resets only the selected layers. (Note: if you don't select any layers, Moho will assume you wish to reset ALL layers, so be careful.)

What 'reset' means is that the layers get the default Flexi-binding setting, so all bones will affect the selected layers.

If you want to limit Flexi-binding of the layers to specific bones, you can select all the layers you wish to bind, the bones you wish to bind them to, and choose Use Selected Bones for Flexi-binding. This will bind the entire selection of layers to the selected bones in one go. Very convenient!

Note: the above steps work for Moho 14 as well, but Use Selected Bones For Flexi-binding has been renamed Link Bones, and instead of selecting a menu command, you can simply click the Link Bones button, which is even more convenient!
