I’m new to rigging. I’m trying to put a rig together for a piece that I’m trying to finish up. I found these videos by DanPro on youtube:
I feel like I was able to follow along well, but when I got to part 3 I’m noticing that it looks like my FK rig is not affecting my tentacle’s mesh when I move/rotate any of the bones on the FK control rig. It works fine with my IK control rig though. I was hoping someone could maybe help me figure out what I’m missing or did incorrectly. (attaching a copy of my .blend file here: https://drive.google.com/file/d/1IIxKxrqhusac3pZo8jNBrbX0bibkxeuu/view?usp=sharing)
I took a little video of how the mesh behaves with IK vs FK as well:
@walt1 Thanks so much for taking a look at my file. I’m glad to hear that it was just some user error on my part. I’m not sure I completely follow though on how to fix what is incorrect in my file. As far as I can tell in the file I provided the MCH.INT.ARM.001 - 011 bones have the deform box in bone properties check boxed to on already like in your screenshot. What am I missing here?
I’m definitely still learning. I’d definitely model a straight tentacle next time around. This originally started as just a sculpt for fun in zbrush, but then I decided I wanted to push it to a complete and textured piece. I figured it was an opportunity to learn something about rigging and also a smart move as opposed to having to retopo/bake/texture 8 bespoke tentacles. I figured easier and more effective to do all that for one tentacle and then pose the other seven to match the pose of the concept.
the fastest way is to rename the vertexgroups from the tentacel
eg DEF.ARM.009 to MCH.INT.ARM.009 and so on at the end these are the groups
MCH.INT.ARM.001 till MCH.INT.ARM.011

all
you find them in the green triangle of the GeometryProperty.
You did all that rig just to make a static pose at the end? That seems to be a huge overkill and waste of time to me…
You could have made that same pose faster in sculpt mode using elastic move and pose brushes and whatnot.
I don’t consider it a waste of time at all. If I learned something that’s all that matters to me. I wanted to learn some more about rigging in blender and so I did. And when I have some time I’d like to play around with potentially animating it. I like to learn and sometimes that leads me down rabbit holes. I’m not claiming anything about efficiency.
I’m aware there are faster ways to pose it. The original high poly sculpt I did was made with zspheres, move brush, snake hook, etc. in zbrush (it didn’t take me too much time to do that). This started off as a lunch time sculpt off a sketch I saw by Stephen Oakley. I decided I wanted to push it further at a later point in time. There are several things I would do different if I was to start a project like this from scratch again that would be more efficient. But anyhow, I do need to check out blender’s sculpting tools at some point too (have yet to do that).
