We can create corrective shapes without a plugin in Maya but it is not a nice way to work. However it's worth going over to see how the Extract Delta plugin works...
1 Duplicate the mesh at the bind pose with everything zeroed.
2. Unlock the attributes
3. Move the duplicated mesh to the side
4. Create a blendshape on the original mesh with "front of chain" in the options
5. Test the blendshape it should make no change to the original mesh.
6. Pose the character in the pose we want to correct
7. Tweak the blendshape mesh until the posed mesh looks good.**
***Step 7 is very tricky in practice.
Now lets move onto the plugin method!

where is the second tutorial?
Thanks. Does Maya have Corrective Smooth modifier like a Blender? It is very nice for animation
Yeah this tutorial is very old and it's all built into Maya now. The newer Blendshape Editor now handles creating the blendshapes automatically and extracting the deltas, so no need for this workflow anymore. Blendshapes in Maya are just a single node, so it's similar but not the same as a modifier.
Maybe lookup some "Blendshape Editor" tutes. "Correctives" is more how you hookup the blendshapes to rigs, you can do that via "Set Driven Keys", or "Pose Interpolator" which is a kind of a RBF solver. Anyways you can lookup "Pose Interpolator".
I use the "braverabbit SHAPES" plugin for all my blendshape work now, it automates everything nicely and handles complex setups. Its for professional setups.

@@andrewsilke1 Thank you. Corrective Smooth in Blender works like Mayas Delta Mush. And Blendshape like Shape Key. Thanks for link
@@olesyanovik2118 ah no, not delta mush, that's something else ;) Extracting Deltas is different from delta mush. Don't worry about what it is, the blendshape editor now handles it!
is that Big Chungus?
I wonder how does its butt perform like
I have problem with the rigs of fatty characters.
Nice... Wouldn't be better to modify the weight map instead though?
+HBMHD skinning weight maps? Nah that would either get intersecting or collapsing areas.
andrew silke Nono, I mean smoothing the weight map itself, or painting/erasing some areas to give the same effect, I've done it before, not on a fat character like this bunny though lol.
yeah that can work sometimes, but on other times it is too tedious or difficult to get right with no assurance of a perfect result. that's why using blendshapes can be better and a time saver as well.
Thanks. So if this is the "manual" method does that mean that there's an "automatic" blend-shapes method? I use Max and plan to also learn Maya sometime.
yes see the next video... 3/7... or look for the Shapes plugin by braverabbit.
Hello, I just want to know how do you model a simple character in order to apply blend shapes on it.
hello I desperately need help with something. This is the second time this has happened to me where i need to start all over. Basically I have a time editor open and I created a new composition for my characters hierarchy named practice for painting weights. This was just to paint the skin weights on my char. After I did all of this, I added some animation nodes and then deleted all of the nodes and composition because I had completed the adding of the weights. Everything was good. And SOMEHOW I keep making it so that even though, there is still a skin cluster for my model, the ctrl shapes, do not have any bind to the character or his joints. So it is as if i have not skinned it yet. Please help
*Andrew Silke* In the blend shape options it doesn't have 'Front of Chain'. I'm using Maya 2018, so what do I use instead?
"After" works fine I think.
I'm not fat, I'm have big bones.
Then the joints are made visible xD
how do you bring up this marking menu for displaying and hiding joints ?
That's a custom marking menu, it comes with the preferences on create3dcharacters.com
Hi ! Can it be solved only by skeletons ?
if you put enough joints in place. You can wire them to set driven keys. Blendshapes are much easier and are fast in Maya, the exception is exporting meshes to game engines, then joints can be handy.
andrew silke Yes , I want to export it to Unity without using Blendshapes. And baking deformation into skin weights also didn’t show good results. So sad..
@@SuperLIGHTMEN Yeah, you just have to be clever with the joint weights, you can use something like the SHAPES plugin, it has a mirror SDK (set driven keys) section too, so it's useful for joints as well as blendshapes. Search for
braverabbit SHAPES
Then find the set driven key tutorials
is this method still the way to go for 2018 maya?
In 2018 this is built in with the new blendshape editor. I use the plugin SHAPES by braverabbit which is much nicer and has more options.
@@andrewsilke1 Can you export with blend shapes to game engine like unreal? And can you make updated tutorial i have Maya 2022
Hi, I had a problem, it's not In this tutorial, I have a flour sack for practice animation, when I raise the curve ctrl up or move it around and I click on bind pose, the character go back to its pose but the ctrl curve stay in place.
When I move the ctrl a little the joint snap to it.
How to let the ctrl curve go back to original pose when I click on bind pose?
Hope you can help me I'm new to maya
Thanks
Please send me Script....
