3 - Expression Testing
Author
In this video I am showing the general shapekey centric workflow to create the different expression tests and expression test building blocks. I'll demonstrate this with simple closed eyes and open mouth shapes. Afterwards we will be setting up drivers to bring them together.

This is just amazing and so well-explained!

Hi @Julien Kaspar. I am stuck here. Something doesn't work and I can't figure out where I am making something wrong. I use 2.81a version. I don`t have in multires sculpt button. I set up everything on 0 in multires and then I open mouth in edit mode. As in your example, weird things happening under the chin so I go to sculpt mode without changing anything and I smooth everything but it looks like I sculpt on multires even if everything is set up on 0. when I go back to object mode it looks like before without my sculpting but when I change multires to higher value it looks as I sculpted. So I close mouth by setting shape key to 0 and now new crazy thing is happening, when I have multires high but fine when I have multires on 0. I don't know is it a bug or me doing something wrong.
Another thing is how do you keep your hidden part in edit mode still hidden in sculpt mode (~5:40)? When I change from edit to sculpt it doesn't keep it hidden.

*@Artur Machura* The reason why the base resolution is not changing and hidden geometry in edit mode is not hidden in sculpt mode is because you are sculpting on the subdivided version of the object.
The "Sculpt" slider is there to define on which subdivision level you are sculpting when entering sculpt mode.
Sculpting on subdivsions will not translate to the lowest resolution automatically. I'm sorry, I forgot to add additional info to the chapter description. In Blender 2.81-2.83 the multires modifier lost the "Sculpt" slider.
So when entering sculpt mode you will always sculpt on the highest subdivision and if you want to sculpt on the base resolution of the object you need to disable the modifier temporarily. Adding the button to quick favourites will help to make this easier.
It's still inconvenient but if you download the experimental version of 2.90, the multires modifier is finally fixed.

*@Julien Kaspar* Thank you. So obvious, why haven't I thought about it. Thank you for the quick reply.

*@Artur Machura* It's obvious once you know it ^^
I will do my best to update some of these videos soon to have this info already in the tutorials.

*@Julien Kaspar* I don't think a lot needs to be updated and it that fix would get its way to 2.83 than probably it could stay as it is. This is the first time I get to the point I didn't know what to do but at this same time, I am not a total beginner so as you put it I may know things that for me are obvious now and I overcome other problems that could be difficult for others.
Any new chapter soon on the horizon?

*@Artur Machura* No new chapter yet. Other projects got more priority and I don't know when I can return to the other chapters.

Hi there i combined my shapekeys together with my eyelids and eyes exactly the way you explained it in the video, but it's not working, when i go into the driver properties of my eye lids the bar where i pasted the path is still highlighted in red and i don't know why, could you maybe help with this?

*@JacoFourienwu* Nevermind i figured it out the 2 values of my shapekeys were different values when i tried to combine it

*@JacoFourienwu* Make sure to use key data blocks and not object or mesh data blocks. Also be sure that the key data block is the right one.

Hey! I'm loving the videos and really enjoying this whole experience!
I'm just stuck in one little part, my character's head doesnt have the right X symmetry, so I did what you suggested and deleted half and applied the mirror modifier again. However, because I cant move the modifier above the multires when I apply the mirror modifier the mirror half looks very patchy:
I've also tried deleting the multi res, applying the mirror modifier and adding the multi res again, however it doesnt have the same high quality as the original multi res:
Is there anything you can suggest i can do?
Julien Kaspar

*@andreanselmo100* That is actually a really good question. If you delete one side, mirror the other and flip the normals manually, then the details from the multires modifier will be broken.
I found a workaround that I should include in this video soon:
In edit mode press F3 and search for "Symmetrize". You can then define which side get's mirrored and it will not break the multires details.
it will still break all Shapekeys though if you have any.

Hello there! This course is great! All of it is gold and i am excited working through every chapter of it. How do i upload images of what i have made from this course?
Julien Kaspar

*@Sosa* Hopefully it will soon get simpler but so far you have to do it like this: https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#images
You essentially just embed an image that is already uploaded somewhere on the internet.

Hey Julien, i imported my model into Blender 2.91 to make use of the sculpt in multi res, however when i add the jaw smoothing and clay it stays present on the model when the mouth is closed, is this supposed to happen? If so I will try a work around and try to shape the vertexes instead??

additionally i actually read more of the comments below and clicked on 'sculpt base mesh' and also reduced all subdivisions to zero whilst sculpting... i think this may have resolved the issue!!
Julien Kaspar

@joanneseale Yes you need to sculpt on the lowest resolution. The toggle for "Sculpt Base Mesh" sadly doesn't work with shapekeys. What that toggle does is it lets you sculpt on the lowest resolution while seeing the higher ones.

Hello, I am stuck again, I am using Blender 2.91 when I right click on the eyelash, closed eye, shape key I do not have all the menu choices and there is no Add Driver menu selection.

ok sorry i once again read a bit further down through the comments and saw that i needed to click on the value of the shape key not the name...

hello, I'm a bit confused, why doing the expression shapekeys before the clean retopology? does it mean we can't really use the animation in production? I'm really looking for a rigging and animation tutoriel. thanks in advance
Julien Kaspar

*@Nly Arivony* I think I did a poor job explaining this in the introduction of the chapter.
To reiterate on the reasons why this step exists in the character creation:
In past movie productions it happened that we designed, modeled and rigged a character before even figuring out the exact animation style. This caused huge problems during the animation, since the model was not fully supporting all the deformations that needed to happen.
Doing some early expression tests for sculpting has 3 purposes.
Unfortunately there won't be a rigging tutorial attached to this character but the animation fundamentals course might still add some videos using the Rain rig :)

Hi, I wanted to add Driver but RMB context menu does not show like below picture. I followed process so I do not know why it is not displayed on my blender 2.83. I suspected to changed "Add Driver" from 2.83 then went to the manual below but it seems not changed. I also tried to Ctrl + D but nothing showed up. Could you please help me why it is not shown to me?

*@madonna* Perhaps you right clicked on the name instead of the value of the shapekey?
I'm also going to make an update video on this but as a tip: Use the "Copy as New Driver" and then just paste the driver on the other shapekeys instead of going through all the steps manually.
This will save a lot of time.

*@Julien Kaspar* Hi Julien, you are right!. Thank you very much to your response. I also tried to downgrade Blender but nothing change. it is very much aha! Once you told me it is very much easy... I can keep going on the tutorial now. Thank you very much again!
