This is exactly what I want for my dinosaur models. Thank you. I was quite curious how the riggers and animators could deform and animate the dinosaurs. From what I've seen with some behind the scene's footage of some dinosaur documentaries and Jurassic Park series, the rigs the animators' use were quite complex, and I want to know how they do it, especially with the legs. Once again, thank you for the tutorial.

Amazing tutorial Pierrick I really enjoy your teachings. I went a little crazy there trying to figure out why my bone roll feature wasn't working. But after really thinking about each step of the rig that you setup I realized my mistake occurred during the creation of the MCH Secondary Bones. During the duplication step I moved the wrong copy of the MCH bones to the new bone layer and the tweak bones were parented to the old MCH Bone Layer not the new MCH INT Bone Layer. I hope this explanation helps anyone else having this issue.

This is a pretty cool solution for getting better control over the pose for the hind leg. The only unfortunate issue with it is the double ik popping that occurs when one of the ik chains reach their full length before the other. I wonder if some sort of soft ik can be used to reduce it.

@Bloodsong13T 2 жыл бұрын

if you unparent the new ik bone, then change its parent BEFORE you create the ik control, it will create a circular dependency, which may royally screw you down the road. in my experiments, you MUST follow the steps in this order to avoid that: 1: extrude the control bone. unparent it. 2: create the IK constraint 3: parent the control bone to the root.

Great ! Do you think it could be adapted to the front leg, which has a scapula in more? Est-ce que ce rig pourrait être transposé à un membre antérieur de quadrupède, qui dispose en plus d'une scapula (omoplate)? Bravo pour tous ces tutos super bien fait en tout cas !

Hi! I bought your rigging course and so far it was exactly what I was looking for. Thank you so much! I was wondering why you chose doing the course in english, considering there's a lot of french animation. I'm curious because I'm also in the process of making my own online art courses and I am about to decide whether I do them in english or spanish.

@PierrickPicaut_P2DESIGN 3 жыл бұрын

Because the french market is so small. There are users all over the world and English is the most comon used languaged :) So English is the best to get a broader audience

@Flandelacasa 3 жыл бұрын

Pierrick Picaut Oh! I didn’t know that, I was under the assumption that the french animation market was big. Yeah, I guess if you’re using Blender and you would like to learn it online, you would do it in english anyway because the tool terms are in english and most tutorials are already in english. Thank you for your response, it has been very helpful!

This is the second time I watch this video and I couldn’t make it to the end, I find it really complicated to make such simple thing “dog leg” behave the way it supposed to, I watched a similar video for maya and it was so easy and straight forward where the person presented 6 different approaches to make a dog leg like and he used two different ik solver algorithms, anyway the results is good but can you make a simplified version that can get the job done? I use rigify and you’re right I’m having trouble switching between poses especially when they’re extreme poses. Thanks.

Another excellent tut, PP. I'm currently rigging a mech with this leg type. I'm wondering, for the legs n arms, if it matters if X or Y or Z is pointing forward? I'm asking because when using IK and pole target it's the x axis that's looking at the pole. If we recalculate bone roll for the arms n legs to have x pointing forward then they won't flip when adding pole targets.

Anyone else having issues with the Foot Rotation technique at 11:50? I followed the instructions to the T, but the leg doesn't follow at all. It's a separate bone system that the Target bone doesn't seem to follow. Know a fix? T-T

@michaeldartashov512 11 ай бұрын

Thank you so much for the great tutorial! But I have a problem, I repeated the lesson several times and every time the CTRL-FOOT-ROT bone does not work for me, the whole chain of bones (MCH-INT_'name of the bone') associated with this bone works, but there is no transmission of the rotation of the CTRL-FOOT-ROT bone to the leg, it seems I'm missed something, but I can't find where I'm making a mistake. Everything else works great.

hey pierrick! Do you perhaps know the solution to my problem? Since 2.8 I haven't been able to select bones within bones except by clicking it a bunch of times. (Like when you use intermediate bones or mechanims bones) While you usually just click the inner bone with 100% succes. I tried unchecking "open GL depth picking" in preferences that only works sometimes(suggested on random website). Wireframe for armature in viewport display is already on... It used to work so good but since latest releases I can't find a solution anywhere. And for assigning constraints and parenting its so useful.

Hi Mate, same for me. Since 2.8 it has been a pain to select bones for me too. I got use to it and hide and unhide bone very oftenly. It was definitely better on 2.7.... got to make some reserch

So when you said I did keep offset but you do connected instead did you mean Specifically only connected between the mechanics bone chain or also the tweakers to the mechanics bones above them. Also I'm having odd behaviour where whenever I move the controllers right click it resets the controller position but the rig has odd transformation left. Similarly in pose mode when using alt-grs I have to spam it multiple time to get to the actual zero state? Anyone else experiencing this/clues as to what I fucked up? Hmm I'm also noticing my TGT, MCH, and MCH INT chains aren't staying perfectly aligned and moving the root bone in pose mode makes the whole chain wobble. Guess I'll have to try again tomorrow I probably fucked up at some point.

@PierrickPicaut_P2DESIGN 3 жыл бұрын

Hi, I meant the mechanism bone specificaly. So that the IK can work. It seems, from what I4ve read, that you have a lot of circular dependency. So you've probably parented the wrong bones together.

@3Rton 3 жыл бұрын

@@PierrickPicaut_P2DESIGN Okay went through it a second time and now I think the chains are mostly behaving but I've got some final questions if you could honor me with one more reply: - At the end you say you move the root bone back to the center of the rig but I don't see you doing this in the video? Would this just mean unparenting the first child of the root, moving it, and then re-parenting the first child to the root bone? - For the Foot roll controller I notice it only moves the MCH-INT chain. This seems to also be the case in the video at the end when you test it. However, what confuses me is then which bones exactly do you use for skinning the mesh? I was under the impression I would do all the skinning with DEF- bones but if the foot roll does only move the MCH-INT chain (I haven't just missed something) then Im supposed to skin with the MCH-INT bones right? EDIT: 4th watch through. I still don't get this. If I skin to DEF bones I get tweakers and IK but no Foot Roll because I still can't figure out how how the foot roll chain translates back to the other ones. If I skin to MCH-INT- bones I get IK and Foot roll, but then of course the tweakers don't work. EDIT: For now I've changed the parent of the MCHTWEAK- bones (Created to fix the scale for the CTRLTWEAK bones via the root bone in the last Q of the video) from MCH bones to MCH-INT bones instead this seems to give both behaviours for now. - How would you recommend mirroring this set-up? My initial intuition would be to Add L prefix to each bone, duplicate them, mirror over 3D cursor, Batch rename 'L'->'R' but.... I also feel like this would potentially open whole can of worms? Am I over worrying or is there tested and safe way to mirror rig parts? Thank you for this video. I bought your rigging course awhile back but haven't made much progress since it feels like too big of a bite to handle. This kind of bite sized video was more comfortable to process!

Instead of adding an extra IK chain to limit the knee rotation, why not add a Limit Distance constraint to the IK bone targeting the thigh? I've tested it with a couple of Limit Distance constraints, one for the inside and the other for the outside clamp regions and it achieves the same effect.
