flexi-bind image

[p8guitar]

I've got a layer with an image of an arm. I created two bones for the layer. Now I want to bend the lower part of the arm with the lower bone. The upper bone should fix the upper part of the arm in place. How do I do that? I think this should work with flexi-binding the two bones to the layer. I selected both bones, then I selected the layer and chose bone - flexi bind layer. Apparently this is not the right way to do this...
When I move the lower bone, the whole layer is rotated instead of bent.

You probably need Bone>Use selected bones for flexi-binding.

I haven't looked at the project file yet, but based on what I see in the image, it looks like you've bound the image to only the lower bone.

Do this first: Select the Image layer and choose Reset All Bone Rigging. This will reset it to the default Flexi-bind. Since this is the only artwork inside this bone layer, it should work fine. You can adjust the bone strengths to affect how 'soft' or 'hard' the bend it at the joint.

Normally, however, all your artwork should be under one bone layer. In which case, you should do what Wes described: Select the arm image layer, then select the two arm bones and choose Use Selected Bones For Flexi-binding. This will bind the art to only those two bones. You'll want to use this or other discreet binding methods for all the artwork, otherwise they will be affected by the default Flexi-bind method. There's nothing wrong with that, but when you want to isolate the affects of certain bones to certain artwork layers, you'll want to use one of the other binding methods. (i.e., Selective Flexi-bind, Point Bind, Layer Bind, or Smooth Joint.)

If I have time this afternoon, I'll take a look at your file.

yes, now the arm is bent, thanks!
When I select "use selected bones for flexi binding" the checkmark for "flexi bind layer" is removed, does that make sense? I'm still flexi-binding the layer?

They are two different modes.

Flexi-bind is a global binding method; it means all of the bones in the Bone layer that have strength will affect the artwork. This is the default method.

Use Selected Bones for Flexi-binding (what I like to call Selective Flexi-bind for short) constrains the flexi-bind to only the selected bones. You can tell this is in effect by looking at the bones: each bone in the Selective Flexi-bind selection will have slightly bolder look. (This is different from the heavy bold look seen when Layer bind is used.)

Usually, you don't want to rely only on Flexi-bind alone in a character rig because it's hard to prevent unwanted deformation from other bones in the rig.

Selective Flexi-bind makes a full character rig easier to set up by eliminating influence from bones outside of the selection.

The default Flexi-bind method works well enough with simple setups.

Selective Flexi-bind is useful in more complex rigs, like characters with multiple jointed limbs.

Hope this helps.

Yeah, two different things. TBH, Flexi-bind Layer isn't very useful.
